Changzhou Pinzheng chicken essence production line technology has reached the domestic LX level

　　Changzhou Pinzheng Drying Equipment Co., Ltd., a national high-tech enterprise, has developed a new type of chicken essence production line aiming at the development of the chicken essence industry and the demand of consumers for chicken essence. It organically combines weighing and batching, mixing, crushing, granulating, drying, screening, packaging and other processes to achieve automatic production, improve production efficiency and product quality, reduce labor intensity and production costs, and increase airtight performance, It avoids the pollution of materials and environment, makes the production process more in line with GMP specifications, and makes the quality of chicken essence more in line with consumer taste and health requirements. At present, the company has produced dozens of chicken essence production lines and put them on the market. They operate normally and have good effects. The company's mixing production line with automatic weighing and weight distribution function has obtained the national utility model patent and invention patent respectively. The technology of improved and innovative design and manufacture of vibrating fluidized bed dryer has reached the domestic LX level.

　　Over the years, the company has carried out all-round cooperation with many domestic food scientific research institutions and colleges and universities, focusing on solving the problems of chicken essence formula, process and equipment as well as drying temperature, providing enterprises with different chicken essence formula, process, plant planning and other services, and providing high-quality production lines, so that users can obtain ZJ's formula, process and equipment, produce high-quality chicken essence products, and obtain higher economic benefits.

　　The raw materials of chicken essence mainly include grain, monosodium glutamate, chicken powder, edible spices, edible salt, etc. The production process of chicken essence mainly includes weighing ingredients, granulation, drying, etc. Before granulation and drying, it is necessary to weigh the ingredients according to different proportions. The traditional weighing ingredients need to be manually weighed one by one, and then poured into the silo. This method has the disadvantages of deviation, low efficiency and high labor intensity of workers. The company invented a mixing production line with the function of automatic weighing and weighing to overcome the above defects. By setting multiple weighing silos and automatic weighing detectors on the second floor of the workbench, and connecting the automatic feeding device, the screw feeder is used for feeding, and the PLC control system is used for operation. At the same time, a PLC display warning device is also installed on the first floor of the workbench to monitor the consumption of materials inside each weighing material on the second floor of the workbench in real time, Timely supply of materials that have been consumed improves work efficiency, reduces labor intensity of workers, reduces deviations in material proportioning, and ensures product quality of materials proportioned as required.

　　The key process of chicken essence production is drying. Since the main component of chicken essence is sodium glutamate, which will become the focus when the temperature is higher than 120 ℃, and is harmful to human health after eating, the temperature of the drying room must be controlled below 120 ℃ when chicken essence is dried, so as to give full play to the nutritional value of chicken essence. If the drying temperature is too low, the drying speed will be reduced. In addition, in view of the characteristics of the chicken essence formed by extrusion and granulation in the production line, such as certain viscosity, high surface moisture and high surface moisture, the method of subsection heating and temperature control is adopted to ensure the quality of chicken essence and work efficiency: that is, the DY section adopts low temperature and large air volume pre-drying, so that the surface moisture of chicken essence is rapidly reduced, and the surface viscosity is also reduced; The second stage adopts medium temperature and large air volume drying to further reduce the surface moisture of chicken essence; The third stage adopts medium-temperature conventional air drying to make chicken essence have sufficient residence time in the fluidized bed to get effective drying; The fourth section is cooled by large air volume, which is convenient for direct packaging of chicken essence after screening. If the three-stage drying method is adopted, good results can also be achieved: the pre-drying stage uses a high pressure and low air volume fan to completely fluidize the wet chicken essence particles; Low-pressure and high-air blower is adopted in the drying section to make the water taken away in unit time more and dry evenly; The cooling section adopts high air volume fan, which can quickly take away heat, reduce product temperature and facilitate subsequent packaging process. The company increases the volume of the fluidized bed boiling chamber to improve the fluidization effect of chicken essence during drying. The hole pattern of the paving bed plate adopts a combined structure: the front section is a tongue-shaped hole, which makes the material move forward smoothly without leakage; The middle and rear sections are straight holes, which make the penetration rate of hot air higher and the heat exchange more sufficient. Its upper and lower bed bodies adopt quick-opening frame structure, which changes the traditional form of bolt fixation and greatly facilitates the thorough cleaning of the system. The lower bed body is supported by stainless steel seamless steel pipe, which makes the bed body structure stronger and has a longer service life.

　　The chicken essence production line of Changzhou Pinzheng Company is also applicable to the production of pigeon essence, crab essence, shrimp essence, mushroom essence, clam essence and other granular condiments, as well as the production of granular drugs and food such as indigo root and sour plum crystal.
