Description

Technical Field

[0001] The utility model belongs to the technical field of food additive production, in particular to a food additive raw material buffer tank with high-precision proportioning. Background Art

[0002] Food additives are artificial or natural substances added to food to improve food quality and color, aroma and taste, as well as for the needs of preservation, freshness and processing technology. Food additive raw material buffer tanks play an important role in the production process of food additives, ensuring a stable supply of raw materials in the production process of food additives. Since there may be certain uncertainties in the procurement and transportation of raw materials, buffer tanks can store a certain amount of raw materials. When the upstream supply fluctuates, the raw materials are replenished in time to ensure the continuous operation of the production line and adjust the flow of raw materials. Different production processes may have different requirements for the flow of raw materials. The buffer tank can control the outflow rate of the raw materials by adjusting the opening of the outlet valve to match it with the requirements of the production process. Some buffer tanks also have mixing and homogenizing functions. For some food additive production processes that require the mixing of multiple raw materials, the buffer tank can store the raw materials while performing preliminary mixing of different raw materials to improve the efficiency of subsequent production processes and product quality.

[0003] In the prior art, when the food additive raw material buffer tank is mixing ingredients, some liquid raw materials and powdered raw materials are easily attached to the inner wall of the transmission pipe, which causes a certain deviation in the raw material ratio and affects the quality of the food additives.
