2. Working principle of gluten dryer

Wheat gluten is made from wet gluten. The wet gluten contains too much water and has a strong viscosity, so it is difficult to dry. During the drying process, you cannot use too high a temperature to dry, because the temperature will be too high. Destroying its original properties and reducing its reducibility, the gluten powder produced cannot achieve a water absorption rate of 150%. In order to make the product meet the standard, low-temperature drying method must be used to solve the problem. The entire system of the dryer is a cyclic drying method, which means that the dry powder is recycled and screened, and the unqualified materials are recycled and dried. The system requires that the exhaust gas temperature does not exceed 55-65°C. The drying temperature used by this machine is 140 -160℃.


3. Instructions for use of gluten dryer

There are many techniques during the operation of the gluten dryer. Let’s start with the feed:

1. Before feeding, turn on the drying fan so that the temperature of the hot air plays a preheating role in the entire system. After the temperature of the hot air furnace is stable, check whether the operation of each part of the machine is normal. After confirming that it is normal, start the loading machine. First add 300 kilograms of dry gluten for bottom circulation, then add wet gluten into the wet and dry mixer. The wet gluten and dry gluten are mixed into a loose state through the dry and wet mixer, and then automatically enter the feeding pipe and enter the drying process. Tower drying.

2. After entering the drying room, it uses centrifugal force to continuously collide with the volute enclosure, crush it again to make it more refined, and then enters the drying fan through the lifter.

3. The dried coarse gluten powder must be screened, and the fine powder screened out can be marketed as finished product. The coarse powder on the screen returns to the feeding pipe for circulation and drying again.

4. Using the negative pressure drying process, there is no clogging of materials in the classifier and bag recycler. Only a small amount of fine powder enters the bag recycler, which reduces the load of the filter bag and extends the replacement cycle. In order to completely recycle the product, a bag-type pulse recycler is designed. The pulse meter controls the entry of compressed air every time the dust bag is discharged. It is sprayed once every 5-10 seconds. The dry powder around the bag falls into the bottom of the tank and is recycled into the bag through the closed fan. .

4. Precautions

1. The exhaust gas temperature must be strictly controlled, 55-65℃.

2. When loading the circulating system, the dry and wet materials must be evenly matched, neither too much nor too little. Failure to comply with the operation will cause instability in the system. Do not adjust the feeding machine speed after it is stable.

3. Pay attention to observe whether the motors of each machine are running normally and detect the current. They should not be overloaded.

4. Replace the engine oil and gear oil once the machine reducer is running for 1-3 months, and add butter to the motor bearings.

5. When changing shifts, machine hygiene must be maintained.

6. Operators at each position are not allowed to leave their posts without authorization. Workers who are not in their own position are not allowed to start the machine indiscriminately, and workers are not allowed to tamper with the power distribution cabinet. Electricians must operate and repair it, otherwise, major accidents will occur.

7. The finished gluten flour after drying cannot be sealed immediately. It must be opened to allow the heat to escape before sealing. When workers get off work, the finished products are handed over to the warehouse.
