The working principle and operating points of the water chestnut sugar coating machine
Date: 2025-10-22Read: 2
The water chestnut sugar coating machine is a commonly used equipment for coating solid materials such as tablets and pills with sugar. By rotating the pot and rolling the animal materials, combined with sugar coating liquid application and drying treatment, a uniform sugar coating layer is formed. The following introduces the core information of the device from two aspects: the working principle and the key points of operation.
1、 Equipment working principle
1Overall operational logic
The BY300/300A-600/600A water chestnut sugar coating machine is named after its pot shape resembling water chestnuts. By rotating the pot and rolling the animal material, combined with the application and drying of sugar coating liquid, the sugar coating liquid evenly wraps around the surface of the material and solidifies, forming a smooth and uniform sugar coating layer. It is suitable for sugar coating processing of tablets and pills.
2Core work process
•Material flipping and mixingAfter the device is started, the motor drives the pot to rotate at the set speed, and the pot is tilted at an adjustable angle, allowing the materials inside the pot to continuously roll and slide with the rotation of the pot, achieving uniform mixing and laying the foundation for even coverage of the sugar coating liquid, avoiding uneven thickness of the sugar coating caused by local accumulation.
•Application and distribution of sugar coating solutionThe operator evenly sprays the prepared sugar coating solution onto the rolling surface of the material through the spray gun or sprayer above the pot. The continuous flipping of the material causes the sugar coating solution to gradually spread, covering each particle of material to form a preliminary sugar coating film. During the process, the spraying speed needs to be controlled to avoid material adhesion and clumping.
•Drying and solidification moldingThe outside of the pot is equipped with a heating device, or clean hot air is introduced into the pot to heat and dry the material wrapped in sugar coating liquid. Heat is conducted through the pot or hot air acts on the material, causing the water in the sugar coating to evaporate rapidly, and the sugar coating layer gradually solidifies and hardens; Continuous rolling of materials can keep the sugar coating layer uniform, ultimately forming a smooth surface and consistent thickness of the finished sugar coating.
2、 Key points for use and operation
1Material preparation and deployment
Before release, it is necessary to ensure that the surface of the material to be coated is dry, undamaged, and the particle size difference is small to avoid affecting the sugar coating effect; Control the amount of materials added according to the specifications of the pot body, usually not exceeding 2/3 of the effective volume of the pot body, to prevent energy waste caused by insufficient or insufficient flipping due to excessive materials.
When adding materials, slowly pour them into the pot to avoid impacting the pot at once. At the same time, check whether there are any impurities or residues in the pot to ensure that the materials are clean.
2Parameter adjustment and process control
•speed adjustmentAdjust the pot rotation speed according to the size of the material and the characteristics of the sugar coating liquid. When the particle size of the material is small or the viscosity of the sugar coating liquid is high, reduce the rotation speed appropriately to avoid the material being thrown out or the sugar coating liquid splashing; When the particle size of the material is large, increase the speed appropriately to ensure sufficient flipping.
•temperature controlThe drying temperature should be set according to the type of sugar coating solution to avoid cracking and discoloration of the sugar coating layer caused by high temperature, or slow drying and adhesion of the sugar coating layer caused by low temperature; During the process, the temperature is monitored in real time through temperature control instruments, and the output of the heating device is adjusted in a timely manner.
•Sugar coating liquid managementSugar coating solution should be prepared uniformly according to the formula in advance to ensure no particle precipitation; When spraying, maintain a moderate distance between the spray gun or sprayer and the material, and the spraying direction should be consistent with the rolling direction of the material to reduce the waste of sugar coating liquid and the pollution inside the pot.
3Cleaning and maintenance
After each use, wait for the pot to cool to room temperature and wipe the inner wall of the pot with a clean damp cloth to remove residual sugar coating and material debris; When there are stubborn residues, soak them in warm water first and then clean them, avoiding scratching the pot body with a hard brush to prevent damage to the pot wall and affecting the subsequent sugar coating effect.
Regularly inspect the transmission components of the equipment to check for looseness and wear, and promptly replenish lubricating oil; Check if the heating device and temperature control system are working properly to ensure stable operation and extend the service life of the equipment.
