A method for automatic on-line production of water chestnut coating pan

Abstract

The invention discloses a method for automatic production-line production of a water chestnut coating pan. The method comprises the following steps: (1) automatically feeding liquid; (2) feeding powder; (3) drying; (4) repeating the steps (1) to (3), and circularly feeding the liquid and the powder into the water chestnut coating pan, and drying until coating is finished; (5) washing a system. The method disclosed by the invention has the following beneficial effects that a manual operation manner is completely changed, and automatic control of a production process is realized, so that the consistency of process control of the product is ensured, and the consistency of quality of the product is guaranteed; manual operation content is reduced, even eliminated thoroughly, and the quantity of operators is greatly reduced; a dustless operation process is realized by adopting a sealed automatic feeding manner, a negative-pressure system with exhausting greater than air feeding, a manner of sealing the water chestnut coating pan and the like; dust exposure is eliminated, cross contamination risks are prevented, and labor safety levels of workers are improved.

Description

technical field [0001] The present invention relates to a method and device for sugar-coating medicine and food, in particular to a water chestnut coating pan, a process and equipment for adding powder and slurry separately to realize automatic control of the coating process - including automatic quantitative feeding of powder and slurry, and The coating process is dried and ventilated. Background technique [0002] The water chestnut coating pot sugar coating process is widely used in enteric-coated tablets, traditional Chinese medicine tablets and food sugar-coated granules and other products. [0003] The current production process is: isolation layer slurry + talc powder, generally 4-5 layers → coating layer slurry + talc powder, generally 15-18 layers → color layer slurry, generally 10-15 layers → colored sugar coating layer 8- 15 floors. The coating process of each layer is slurry→talc powder→drying. The amount of feeding and drying time each time stipulate a range, ...

AI Technical Summary

Problems solved by technology

[0004] Such a process has the following problems: 1. A large amount of dust exposure: manual use of stainless steel spoons and other utensils for feeding, the dust exposure in the operation room is serious, which can neither avoid cross-contamination in GMP requirements, but also has labor safety problems; 2. Control the amount of feeding according to experience , Extensive feeding method: 1 tablespoon of material is poured directly, resulting in difficult control of product batch and inter-batch differences; 3. The production steps are cumbersome and long, and the labor intensity is high; 4. High requirements for operators' experience; 5. Incomplete clearance
