Furthermore, the mixing equipment should operate safely, be easy to operate, save energy, and reduce labor costs. - **Q: How to solve the problem of horizontal seal sticking to the knife of the vertical packaging machine** A: First of all, we need to understand the sealing mode of the packaging machine: first, the horizontal seal is heated by the heating tube to seal the plastic film. The horizontal seal has a built-in cutter, and the cutter extends to cut the bag when sealing. The horizontal seal sticking to the cutter has a lot to do with temperature and film. 1. The temperature is too high, causing the film to melt and adhere to the horizontal seal. When the cutter extends, the melted film will adhere to the cutter. At this time, we can wipe the horizontal seal position clean with a brush, and at the same time, adjust the temperature of the horizontal seal, and then try to pack. 2. In addition to controlling the temperature, the sealing time also needs to be considered. Too long will also cause the above problems. - **Q: What are the disadvantages of using a belt dryer?** A: 1. Large space requirement: They occupy significant floor space. 2. Potential for uneven drying: If not properly loaded, the material might not dry uniformly. 3. Maintenance: Requires regular cleaning to avoid cross-contamination, especially in food and pharmaceutical applications. - **Q: Differences between belt dryer and hot air circulation oven** A: 1. Belt dryer has transmission device, while hot air circulation oven does not, which is determined by the design principle of the equipment. 2. Hot air circulation oven loading requires manual placement of materials on the baking tray, and then placing the baking tray on the drying cart and pushing it into the oven, while belt dryer can achieve automatic drying, and the material can be dropped onto the mesh belt through the feeder. 3. Hot air circulation oven is an intermittent production equipment, while belt dryer is a continuous drying equipment. 4. Hot air circulation oven is suitable for small batch production, while belt dryer is suitable for large batch continuous production.
