Review all of products valve in Naman Tech

#1. Review of knife gate valve

Here are some types of knife gate valves available at naman-tech. It is best to get the appropriate gate valve for a particular application.

Plastic knife gate valves

Common gate valves are only used for the lowest pressure applications for aquaculture such as simple irrigation or plumbing and aquarium pipes and other similar applications. These gate valves can only hold a maximum of 30 PSI and at least 10 PSI for larger units because the resin is not as durable as steel. The good thing about this type of valve is that they are much cheaper than steel so even if one fails or is broken, it is easy to replace.
Brass knife gate valves

A knife gate valve made of brass similar to the type is made of stainless steel casting. However, door valves can withstand higher pressures, especially if the door is made of the same material because the metal is harder than stainless steel. This can also be used with similar applications for those made of stainless steel as it can also withstand corrosion and other elements. The maximum pressure of the brass gate valve can withstand about 300 PSI, twice as much as what stainless steel valves can withstand.

Stainless steel knife gate valves

These gate valves are the most common that we can see on the market today as it is known that stainless steel can pretty much withstand the corrosion and harshness of the elements. However, as a rule, stainless steel gate valves can withstand only 150 PSI to avoid any serious malfunction or other accident that may occur due to the gate valve being damaged.
#2. Solenoid Valve
Direct Acting Valve

The force of the coil opens the valve port by removing the pin from the valve seat. The direct solenoid valve depends on the current level in the coil to operate. This valve opens and closes regardless of flow and pressure under no pressure conditions.
Pilot-Operated Valve

This valve consists of a valve seat and main valve with a vent and main valve diaphragm with the cap. The upper part of the valve includes the driver seat with the corresponding opening. The pilot tower is opened and closed by the plunger. The airflow pressure is used to open and close the valve cover and through the opening. Control valves with control valves always require full power to open and keep open.
Two Way Valve

This valve has an entrance and an exit to facilitate the flow of liquid and turn it off. The operation of the two-way valve solenoid is called ‘normal opening’ and ‘normally closing’. The inlet pipe must have a greater pressure than the outlet to force the liquid through the two-way valve. Equal pressure of two pipes will not facilitate the flow of liquid.
Three Way Valve

This valve has three ports and two holes, one of which opens while the other is closed. The three-way solenoid valve is interchangeable as well as exhaust pressure and is indicated as normally closed, open, or universal.

Types of Actuator and accessory.

Actuator and accessory are mechanical or electro-mechanical devices that provide controlled and sometimes limited motion or Positioner to be operated by electricity, by hand, or by various fluids such as air, hydraulics , etc. The two basic motions are linear and rotational. Linear actuators convert power to linear motion, typical for Positioner applications, and often have a push and pull function.

Some linear actuators are not powered and hand operated by using a rotary knob or hand wheel. The rotary Actuator and accessory converts the power to provide rotational motion. A typical use is the control of different valves such as ball or butterfly. Each actuator has different versions for electrical configurations and has many designs and sizes depending on the application. Linear actuators provide push and pull motions with rigid lugs.

Actuator and accessory usually incorporate motors, cylinders, or other moving devices to produce linear rotation or translation. Assembled and pinion arrangements, ball screws, and other types of transmission components connect the motor, etc. to the load.

Actuators are separated by motion and power. Linear actuators produce push / pull action. Rotary Actuator and accessory produce rotary motion. In many cases, the linear actuator starts with a rotary motor – a typical motor – which rotates into linear motion via a screw or similar device. The reverse is also true: many rotary actuators can start with linear devices such as hydraulic cylinders that produce circular motions through arrangement of racks and gears.

Actuators are widely used to operate valves remotely. A valve equipped with so-called control valves. (See the Valve Buying Guide for a discussion of control valves.) A typical actuator for a global valve needs to be capable of rotating the valve through multiple turns between opening and closing.

Typically, a global valve actuator will consist of an electric motor that drives the gear. Which in turn rotates a nut with the threads of the valve body. Flip-flops such as ball valves usually use pneumatic actuators to push and pull the gearboxes through the gears to allow rotation of the ball, butterfly etc. In short, Valve actuators correspond to the design of the valve they are intended to operate.

Actuators are also used in many linear motion applications where air is not available to control cylinders. Or need more force from the compact design. An abnormal linear drive uses a line that when straight forms a rigid length but can bend around the rudder to get its motion. Other linear motion Actuator and accessory use a belt, a screw, or a rack and pinion to achieve push / pull operation. Linear and rotary actuators generally use coil motors directly.

Selecting actuators supported requires knowing the parameters such as load, stroke length, duration, etc. Many of these parameters have speed limits and force. And narrow the selection according to this way can bring appropriate technology. Other considerations include the types of services available. Hydraulic transmission provides great power at small sizes but requires a hydraulic pressure source.

The actuator uses the available air of the plant but there is a balance made due to the larger size for the equivalent force. Electric actuators have better control and less leakage advantages. Which are advantageous in clean room settings and more economical in the long run. Electric actuators tend to have higher initial cost. They also have the advantage of being installed outdoors, where air systems can freeze.

Pneumatic actuator control valves fall into two camps: dual operation and spring return. Dual action means that air pressure will move the valve in both directions. Spring back means that a spring is used once that the air pressure must pass to open (or close) the valve. It makes a difference how the valve will behave when air pressure is lost. Spring return valves will return the valve to the unused state when the air pressure is lost. Hydraulic valve drives can be fitted in similar fashion.
Actuator and accessory

For motion control, actuators are selected based on speed and accuracy requirements. Some linear actuators are designed for micro Positioner and rely on piezoelectric crystals to produce very small resolution movements that are very useful in the nanometer world of optics, In general, belt drives and screws allow locating the Positioner stages and the like to achieve repeatability measured in milliseconds of an inch.

Some linear actuators are used with manual controls, such as those found in dental chairs and require no other Positioner feedback with limited switches. Some manufacturers even remove the limit switches by providing integrated free-form motion at the end of the stroke, such as the actuators shown on the right.

Pneumatic cylinders are mechanical devices consisting of pistons and assembly bars located in cylindrical boreholes and are limited to the head, operated by air.

Note: What is Pneumatic actuator?

Pneumatic actuator is the compressed air energy converter is formed by vacuum or compressed air at high pressure into linear motion or spinning Compressed air power is desirable for main engine control because it can react quickly at start and stop because the power supply does not need to be stocked to reserve.

Pneumatic actuator drives allow large forces to be generated from relatively small pressure changes. These forces are often used with valves to move the film to affect the flow of liquid through the valve. It is responsible for transforming the pressure into reality.

I am a restaurant business owner for coconut food. So, I am always looking for companies that are capable of providing quality coconut products to us. Thienkhanh is a company that I believe in over 2 years.

Coconuts are prominent products at the Thienkhanh company. Thienkhanh offers a full range of products from coconut such as: desicated coconuts, coconuts oil, nata de coco, … I used a lot of products from this company.

So, from a subjective perspective, I give my personal opinion.

Note: My article is not for the purpose of advertising and earning commissions based on their products. I only give it with my personal comments. Because I’m a loyal customer. They have provided a lot of good products and services for me. That’s why I helped them.
#1. Review the desicated coconuts:

Desicated coconuts are a coconut product that many people in Vietnam know. Most of the food that I use desicated coconuts like: snacks, curry, tea, coconut milk, coconut cream, …
Fresh produce

What surprised me was that the food made with desicated coconuts at Thien Khanh had a wonderful flavor. My food is tastier and smoother.

Why is this happening?

I’ve been asking a lot of questions about this. Later, I learned, it was due to the time and choice of coconut to produce desicated coconuts.

Desicated coconuts should only be used after 3 days of production. After 3 days, desicated coconuts will gradually lose its sweetness and aroma. Therefore, your food will lose its flavor when using desicated coconuts have 3 days production

If you still do not believe what I say, you can look to buy a variety of desicated coconuts at different companies and process their food with them. You will feel what I say.
Fast delivery time

I like the way they serve me. Even though I only put them in a relatively small amount. However, they are still enthusiastic and help me transport orders quickly. I always get my product within 4 hours – 24h. As a restaurant owner, I always want my products to be fresh to serve our customers.

And the delivery time is always top priority. If you are a restaurant business owner, I think you have the same thoughts as me.
#2. Review the coconuts oil:

I often use coconut oil instead of other processed food oils. In addition to making my food more delicious and fragrant, it also helps a lot for our health.

Because in coconut oil contains more than 90% saturated fatty acids, it has the ability to resist oxidation. Due to its high fatty acids, coconut oil helps improve cholesterol and helps in killing bacteria and other pathogens.

I decided to switch to using their coconut oil, when the coconut oil supplier to our restaurant exchanged poor quality. And after using coconut oil, I really love their products more.
Do you know why?

Because of:

Taste better food
Fresh produce
Attractive colors
And there are many more….

#3. Review Nata de coco
What is nata de coco:

Nata de coco is a delicious, delicious, naturally derived, and especially good for health. Coconuts (nata de coco) are the most common food produced by the fermentation of the bacterium Acetobacter Xylinum. This is the food that is applied from bacterial cellulose. The coconut jelly is a dessert dish: Dai, in, very tasty with the chemical nature of polysaccharide, so no high nutritional value, low energy and have high sensory value, good food to reduce the risk of obesity.

Nata de coco – stimulates intestinal motility which makes the regulation of excretion better with very high fiber content which is good for the digestive system to help the body fight colon cancer. This product from coconut has the effect of preventing cancer and can keep the skin smooth.

I know nata de coco from a few of my friends. I tried eating it in a small restaurant in Viet Nam with my friends. Wow! To be honest, I fell in love with it as soon as I ate it and I really enjoyed it to my country, especially the area where I lived. But, this idea has been postponed for a while, because nata de coco is the food that needs to be eaten right after processing, it can not last long.

I learned and processed them myself, but all failed. Actually, I really wanted to promote this food to where I live, but it was really a difficult thing for me.

Until I found the company in Vietnam, I tried to order products from them and use. The taste of the dish echoes me again.

Each company offering nata de coco will give out different products. And I like the taste of nata de coco at thienkhanh. Nata de coco plasticizer, sweet, aromatic and fresh from nature.
The advantages of their coconut products:

Fresh produce
Good price
High quality products
Fast delivery time
Serve enthusiastic service
Employees know about their products

Product defects:

Product packaging is not attractive

In addition to the above shortcomings, I have yet to see any defects in their product.

In short, for me, the coconut products that I use at their company are really good and quality. It brings our pleasure and thoughtful service to our customers. I hope the products in thienkhanh will be developed more widely across the world.

#1. Fish meal & fish maw in Thienkhanh

Thienkhanh is a famous fish meal supplier in Vietnam. We cooperate with the appropriate marine fish processing companies to consume human food into high nutritional value. Our fish meal and fish oil production plants are strictly tested prior to production.

The fisherman, acting independently from the plant manager, catches fish at night and takes it ashore the next morning for processing. The fish meal produced is mostly added to the chicken feed at a 3-10% level, in that it forms an almost irreplaceable ingredient due to its unique essential amino acid composition and presence. of the polyunsaturated fatty acids (PUFA) in the remaining fat.

And the production process uses only steam (in the kitchen) and heat (in the dryer) to create the final two products – fishmeal and fish oil. No chemicals were used except for the ethoxylation (1,2-dihydro-6-ethoxy-2,2,4-trimethylquinoline, EQ), added at 400 mg / kg to protect PUFA in meal.

Therefore, a clean environmentally friendly process and biodegradable waste products. Drying of fishmeal is an important part of this process because PUFA can be oxidized if it is not managed properly. EQ supplementation immediately after drying protects PUFA from oxidation afterwards. The destruction of fish in delays between catching and processing is still a problem, as freezing fish on ships is not economically viable.

Processing damaged fish will inevitably lead to a decrease in the quality of flour and oil and also contribute to air pollution. Continuous efforts have been made to improve fishmeal production and quality, and this review highlights these efforts.
#2. Canned Pineapple

Pineapple (Ananas comosus L.) belongs to the family Bromeliaceae and is one of the most important fruits of trade in the world (Dhar et al., 2008). Pineapples are usually eaten fresh or fresh pineapple juice. Pineapple is a great source of vitamins and minerals, and offers a palette of colors, flavors and textures for fun eating (Othman, 2011). The popularity of pineapple is due to its sweet and sour taste contains 15% sugar, malic and citric acid. It also contains vitamin C and essential minerals, manganese (Okonkwo et al., 2012).

Pineapple originally consumed only as a fresh fruit. With the development of the processing industry, fruits have been processed and consumed in various forms such as chunks, slices, fruit juices, syrups, jam, pineapple and pineapple. Pineapple is the only source of bromelain, a complex proteolytic enzyme used in the pharmaceutical market and as a meat softener, while the waste from fruit processing is now processed into a powdered product. used as a fiber supplement.
Research:

This research was undertaken to create and enhance the sensory and nutritional properties of canned pineapple and its effects after processing and preserving these products.

Pineapple was packed with sugar solution (treated), orange juice mixed with a ratio of 1: 1 water: fruit juices, mango juice diluted with a ratio of 3: 1 water: juice All fillers were increased to 40% by sucrose and then packed in a 2: 1 volume of solution (wt: wt). Results showed that total sugar, ash, total phenol, carotenoids and ascorbic acid content in pumpkin and pineapple were (62.16% and 78.49%), 5.69% and 2.21. %), (3.74% and 4.28%) dry and (0.38% and 0.16%) and (33.81 and 37.79 mg / 100 g) on ​​the basis of fresh weight, respectively .

Results showed that the total dissolved solids, total sugar, total phenol, total carotene and ascorbic acid of canned pumpkin ranged from 17.1% to 19.5%, 89.50% to 97, 49%, 0.87% to 1.47%, 0.42% to 1.27% and ascorbic acid 88.19 to 210.53 mg / 100 g on a dry weight basis. The robustness of canned pumpkin has shown a serious decline due to canning and preservation. In addition, brown rice without enzymes increased slightly during storage without significantly affecting the quality of the product. The chemical composition of canned pineapple has decreased slightly during storage. Statistical analysis for sensory evaluation of canned pineapple with fruit juice especially canned pineapple (Methods 2, 5) achieved a high acceptance score after 6 months of storage at room temperature.

The physical and chemical properties of canned pineapple were investigated. The results show that canned pineapple in thienkhanh has higher value for canned pineapples in other companies and is approximately equal to fresh pineapple. That is what our customers trust and use our products.
#3. Rubber band

Check quality rubber band in thienkhanh before selling

Rubber strips from each batch are tested for quality. One of them is the measurement module, or how hard a band is: a tight band should lift while pulling, while a band does to protect fragile objects so gently step back. Another test, for stretching, determines how far a band will stretch, depending on the percentage of rubber in a band: the more rubber, then the longer it should be.

A third characteristic often tested is the breaking strength, or whether a strip of rubber is strong enough to withstand normal pressure. If 90 percent of the sample strips in a batch pass a specific test, the batch moves to the next test; If 90 percent pass all tests, the batch is considered ready for market.

So, the above are the answers to the questions of the audience have set for thienkhanh about the product quality as well as the production regulations of our company. If you have any questions or need assistance, please contact us immediately to get the best service
