AI Technical Summary

Technical Problem

In the existing pea starch production, powder airflow drying equipment requires complex dehydration treatment, low equipment integration, low energy utilization, and serious starch waste after hot air separation.

Method used

The pre-drying cylinder and spiral filter are combined with the structure. After pre-drying the starch through high temperature and high pressure, the hot air separated by the cyclone separator is used for secondary drying. Combined with the decomposition wheel, the starch is lumped, so as to achieve efficient dehydration of the starch and the recycling of heat.

Benefits of technology

The dehydration process is simplified, the degree of equipment integration is improved, the starch waste is reduced, and the energy utilization and dehydration efficiency is improved.

Abstract

The present invention discloses a powder drying device and method for pea starch production, which relates to the technical field of powder drying. The present invention includes a hot air furnace and a cyclone separator. An air outlet pipe is arranged at the outlet of the hot air furnace, and a connecting pipe is arranged at the air inlet end of the cyclone separator. A drying pipe is rotatably installed between the air outlet pipe and the connecting pipe. A spiral filter is arranged on the outer side of the drying pipe. A plurality of sliding openings are formed on the outer side of the drying pipe. A pre-drying cylinder is sleeved on the outer side of the drying pipe. Through the filtration of the spiral filter, water remains below, and starch is conveyed upward. The starch is conveyed from above to a starch chamber for secondary drying, so that the water content of the starch can be controlled at 35%-40%. Then the starch is sprayed into the air outlet pipe by high-pressure gas and dried in the drying pipe along with the hot air. There is no need to additionally use dehydration equipment, screw conveying equipment and dispersing equipment, and the integration degree of the equipment is high and the structure is compact.
