Sodium glutamate drying fluidized bed

Abstract

The invention provides a sodium glutamate drying fluidized bed which comprises a shell, wherein a partition plate is horizontally arranged at the lower part of the interior of the shell so as to divide the shell into an upper air flow drying chamber and a lower hot air buffer chamber; a feed port and a discharge port are arranged at both ends of the air flow drying chamber respectively; the upper part of the air flow drying chamber is connected with a tail air collecting device; the partition plate is provided with a pneumatic vibrating device; a sieve plate is arranged above the pneumatic vibrating device, and is driven by the pneumatic vibrating device to vibrate; and an air inlet of the pneumatic vibrating device is connected with a hot air source, and an air outlet of the pneumatic vibrating device is communicated with the hot air buffer chamber through the tail air collecting pipe. The sodium glutamate drying fluidized bed employs hot air as a power source and adopts a pneumatic vibrating way, thereby avoiding directly using electricity and reducing energy consumption; and meanwhile, the upper end face of the vibrating sieve plate is provided with an air deflector to change the flow direction of hot air, so that the drying efficiency is greatly improved, and the frequency of occurrences of appearance defects such as crystal mergence, adhesion, difference in end sizes and the like of products is lowered.

Description

technical field [0001] The invention belongs to the technical field of sodium glutamate production equipment, in particular to a sodium glutamate drying fluidized bed. Background technique [0002] Traditional sodium glutamate drying equipment includes belt drying equipment, drum drying equipment, etc., but there are the following defects: on the one hand, due to a combined H contained in the sodium glutamate crystal 2 O molecules are easy to lose when the temperature is too high; on the other hand, the longer the wet sodium glutamate crystals are in contact with each other, the easier it is to crystallize, so it is required to control the drying temperature at 50-80°C and dry quickly. At present, most products are dried using a vibrating fluidized bed. The use of a vibrating fluidized bed meets the special requirements of crystal drying to a certain extent, but there is still a large room for improvement in the drying speed and effect, and the appearance of crystal particle...

[0002] Traditional sodium glutamate drying equipment includes belt drying equipment, drum drying equipment, etc., but there are the following defects: on the one hand, due to a combined H contained in the sodium glutamate crystal 2 O molecules are easy to lose when the temperature is too high; on the other hand, the longer the wet sodium glutamate crystals are in contact with each other, the easier it is to produce parallel crystals, so it is required to control the drying temperature at 50-80°C and dry quickly

At present, most products are dried using a vibrating fluidized bed. The use of a vibrating fluidized bed meets the special requirements of crystal drying to a certain extent, but there is still a large room for improvement in the drying speed and effect, and the appearance of crystal particles.
