High-efficiency albumen powder drying device

Abstract

The invention belongs to the field of edible protein processing and in particular relates to a high-efficiency albumen powder drying device. The device comprises a drying tower, a feeding device, a gas generating device and a discharging device, wherein the drying tower comprises a feeding hole, a discharging hole and an air jet hole; the gas generating device comprises a filter, an air blower and an air heater which are sequentially connected with one another; an outlet of the air heater is connected with the air jet hole; the high-efficiency albumen powder drying device is characterized in that the discharging device comprises a cyclone separator and a preheater; the discharging hole, the cyclone separator and the preheater are sequentially connected with one another; the feeding device comprises a storage tank, a feeding pump and a sprayer which are sequentially connected with one another; an air inlet of the preheater is connected with an outlet of the air blower; the air outlet is communicated with the storage tank. According to the device, heat in tail gas can be recycled, and albumen powder settlement is relatively complete.

Description

technical field [0001] The invention belongs to the field of edible protein processing, and in particular relates to a high-efficiency drying device for protein powder. Background technique [0002] In the food processing industry, the final step of protein powder production is drying, and the commonly used protein powder drying method is spray drying. The drying process is carried out in a drying tower. After the feed liquid is sprayed by a sprayer, it contacts with hot air to evaporate most of the water to form a finished protein powder. [0003] In the protein powder production process of the prior art, the tail gas temperature of the spray drying tower is relatively high, usually at 80-100°C, and the direct discharge of the tail gas will take away a lot of heat, and in the higher temperature tail gas, the protein powder with fine particles cannot be dried. The cyclone dust collector settles down, and the exhaust gas will still entrain part of the protein powder. Conte...
