Abstract

The invention discloses a low-temperature high-efficiency fluidization combined drying process and equipment thereof; the drying equipment comprises an afterheat utilization primary pre-heating device, a secondary drying device, cyclone separators, blowers and a temperature control device; the afterheat utilization primary pre-drying device or the secondary drying device comprises a feed opening, a discharge port, a vent and a drying chamber; the discharge port of the afterheat utilization primary pre-drying device is connected with the feed opening of the secondary drying device; the vent of the afterheat utilization primary pre-drying device is sequentially connected with a cyclone separator A, the secondary drying device, a cyclone separator B, a blower A and the drying chamber of the afterheat utilization primary pre-drying device; the vent of the cyclone separator A is connected with the blower B; and the drying chamber of the secondary drying device is respectively connected with a blower C and the temperature control device. The invention quickly and homogeneously dries material to be dried under the premise of meeting the original quality of raw grain, leavening and other products, has the advantages of energy-saving, environment production, low temperature and high efficiency, meets the requirements of continuous and scale production, and has good process system maintenance performance.

Description

technical field [0001] The invention relates to a drying process and its equipment, in particular to a low-temperature and high-efficiency fluidized combined drying process and its equipment. Background technique [0002] my country is a big country in grain production and comprehensive processing and utilization in the world. According to statistics, my country's annual grain output is about 500 million tons. However, the loss rate of grain in the process of threshing, drying, storage, and transportation after harvest is as high as 15%, far exceeding the 5% standard stipulated by the Food and Agriculture Organization of the United Nations. The loss of grain is as high as 5%. If calculated on the basis of an annual output of 500 million tons of grain, it is equivalent to a loss of 25 million tons of grain. Therefore, the process of grain production and comprehensive processing and utilization has attracted much attention. In terms of technology and equipment, research on lo...
