Description

Technical Field

[0001] The utility model relates to the technical field of food drying machines, in particular to a multi-layer belt-type food drying machine. Background Art

[0002] Food dryers have the advantages of high drying efficiency, simple operation, energy saving and environmental protection. They are widely used in food processing and preservation. They can effectively reduce the moisture content in food, prevent food from getting damp and mildewed, extend the shelf life of food, and also maintain the nutritional content and taste of food.

[0003] Belt dryer is a continuous drying equipment for batch production. It is used for drying sheet, strip and granular materials with good air permeability. It is especially suitable for dehydrated vegetables, catalysts, Chinese herbal medicines and other materials with high moisture content and high temperature. However, the conveyor belt of belt dryer is long and needs to occupy a lot of space. At the same time, because the food is distributed on the conveyor belt, the space for hot air heating of the dryer is also greatly increased, and the drying efficiency is low. For this reason, we propose a multi-layer belt food dryer. Utility Model Content

Then the food to be dried is put into the feed port. Baffle three prevents food from falling from the front end of the uppermost conveyor belt. The diverter block diverts the food so that the stacked food is evenly distributed on the upper surface of the uppermost conveyor belt. Baffles one, two and Baffle plate four blocks the food, slowing down the falling speed of the food while preventing the food from falling from the staggered positions of the vertically adjacent conveyor belts. The food passes through the four conveyor belts in turn. During transportation, the hot air blower starts to deliver hot air to the cabinet.
