Spiral promoting drier

Abstract

The invention relates to a spiral promoting drier, and relates to a drying plant of a material having a biological active substance. The spiral promoting drier is characterized in that a spiral promoting unit body is provided with a shell and a motor, and the periphery of the shell is provided with a heat exchange sleeve with a heating medium inlet and a heating medium outlet; a motor drives a spiral agitator shaft arranged in the inner cavity of the shell, the upside of the front end side wall of the shell is provided with a feed port, and the downside of the rear end side wall of the shell is provided with a discharge hole; a multi-hole spiral piece winds on the spiral agitator shaft, wherein the multi-hole spiral piece penetrates through the two ends of the spiral agitator shaft and multiple air holes are evenly distributed on the multi-hole spiral piece; the upside of the front end side wall of the shell is provided with an air outlet arranged on the front of the feed port, and the upside of the rear end side wall of the shell is provided with an air inlet; the heating medium inlet is arranged on the front end part of the heat exchange sleeve, and the heating medium outlet is arranged on the rear end part of the heat exchange sleeve; and two or multiple spiral promoting unit bodies are connected in series so as to constitute the spiral promoting drier, the drying of a heat-sensitive material with complicated physical properties is solved in large production; and the spiral promoting drier provided by the invention is convenient for installation, transportation and adaptive to various areas.

Description

technical field [0001] The invention relates to a drying equipment, in particular to a drying equipment with complex physical properties and requiring the biological activity of the material to be preserved. Background technique [0002] The physical properties of biohumic acid semi-finished products are very complicated. The semi-finished products are made of mixed fermentation of bagasse and bran. From the perspective of physical properties, they are a combination of short fiber materials, small block materials and powder materials of different thicknesses. formed mixed materials. The biological fulvic acid (FA) and beneficial microorganisms contained in the material are the main effective substances of biological humic acid products. The specific gravity of the material is very light after drying, and the active ingredient of the product - the microbial active substance is heat-sensitive. The maximum tolerance temperature of FA in drying is 100°C (within a few minutes),...

AI Technical Summary

Problems solved by technology

When the semi-finished biological humic acid is dried in the shell, these powdery materials will be sucked away by the exhaust device, and the active ingredients will be greatly lost

In addition, microbial active substances usually survive for a short time in an environment with a temperature of 70°C. If the utility model is used to dry the above-mentioned biological humic acid semi-finished products, it will appear that the drying operation can be completed if the heating temperature is higher than 100°C, but The microbial active substances are completely lost; or the heating temperature is lower than 70°C, which can keep the microbial active substances, but due to the limitation of the length of the spiral stirring shaft and the shell, a complete stroke cannot make the materials complete the embarrassing situation of drying

Even if special measures are taken to make the spiral stirring shaft and housing long enough, such as more than 20 meters long, this super-long spiral stirring shaft and housing are difficult to transport, and this utility model is also difficult to obtain between the manufacturing plants. put into practical use
