Low-air-pressure particle material drying equipment

Abstract

The invention discloses a granular material drying equipment under low air pressure state, which comprises a suction pipe, a drying cylinder body and a blowing hole. Sleeve, shock-absorbing spring and T-shaped rod; both ends of the drying cylinder are welded with end sealing plates, and a closed drying chamber is formed between the drying cylinder and the end sealing plates, and the drying cylinder The top front end is welded with a material adding pipe; the heat preservation effect is good, the sealing effect is good, the spiral blade and the scraper blade stir the material in the drying cylinder to ensure the full mixing of the material in the drying cylinder, realize the circulation of hot air, and improve the heating of the material. The uniformity of the material, and in the low pressure environment in the drying cylinder, only a low heating temperature can make the water in the material reach the boiling point to evaporate and separate, which improves the efficiency of material drying, reduces the drying cost, and improves the quality of the material. Ease of drying.

Description

technical field [0001] The invention relates to the technical field of drying equipment, in particular to a granular material drying equipment under low air pressure. Background technique [0002] In the field of production and processing technology, material drying refers to a process of heating and evaporating water contained in solid particles such as grains, plastic granules, coal mine granules, medicinal material granules, feed granules, etc. into a gaseous state and separating them from solid particles. It is widely used in food, injection molding, coal mining, traditional Chinese medicine, breeding and other fields. At present, the drying equipment for granular materials is usually heated and dried by hot air method. After the air is heated by burning straw, coal or electric heating, it is blown into the material to evaporate the water in it to achieve dehydration. However, this heating method consumes a lot of energy. The temperature of the material must be heated a...

Problems solved by technology

At present, the drying equipment for granular materials is usually heated and dried by hot air method. After the air is heated by burning straw, coal or electric heating, it is blown into the material to evaporate the water in it to achieve dehydration. However, this heating method consumes a lot of energy. The temperature of the material must be heated above the boiling point of water (the boiling point of water at atmospheric pressure is 100°C) to evaporate the water in the material, which requires a lot of energy consumption, and the activity or composition of the material may be damaged if the temperature is too high, such as destroying The activity of Chinese herbal medicine granules, high temperature melts plastic granules or destroys the nutritional value of feed granules
