Description

The invention relates to a technique for drying powdered products, proprietary milk powder, and can be used in the dairy, food, chemical and other industries. A well-known installation for drying bulk materials, containing vibrating dryers with gas distribution grids, cyclically installed on the exhaust coolant line, units for input and output of coolant, loading and unloading of the product 1 .. The disadvantages of this installation are a lot of product carryover and poor quality. Closest to the present invention is a vibrating dryer, comprising a housing, with a gas distribution grill and nozzles for entering and discharging the drying agent, loading and unloading units for the dried material, and a device for cleaning the spent drying agent G2. The disadvantages of the known apparatus are also large ablation and low quality of the product due to abrasion. “The purpose of the invention is to reduce ablation and improve the quality of drying. The goal is achieved by the fact that in a vibrating dryer, comprising a housing with gas distribution grill and drying agent input and output nozzles, nodes for loading and unloading dried material and a device for cleaning the spent drying agent, is arranged as horizontal above the hull a cylinder having an inlet swirler and a longitudinal chute in the lower part, with the outlet cylinder communicating with the outlet nozzle of the drying agent and the discharge unit. In this case, the output cylinder can be equipped with a baffle and an ejector. FIG. 1 is schematically depicted in a vibratory drying apparatus; in fig. 2 shows section A-A in FIG. one; in fig. 5 section bb in FIG. 1. The apparatus includes a housing 1 having a gas distribution grill 99 2, loading units 3 and unloading 4 of the material being dried, connection pipes 5 and output 6 of the drying agent, elastic elements 7, aerial drive 8, device 9 for cleaning the spent drying agent, consisting of a horizontal cylinder 10, having (swirl / 1 11 and chute 12. The apparatus can be equipped with a chimney 13 and an ecu- rus. Swirl 11 can be made in the form of a flap 15. Vibration drying apparatus works as follows way. Dried matter L, for example, milk powder that needs to be dried or cooled, the loading unit 3 enters the apparatus and, due to vibration generated by the vibrating actuator 8 and elastic elements 7, moves along the gas distribution grid 2 to the discharge unit k. Drying agent (air ), prednazhenny for drying or cooling the material, through the nozzle 5 for the introduction of air is directed into the housing 1, passes through the perforation of the gas distribution grid 2 and the layer of material being processed. Under the influence of vibration and the flow of air blown through the bed, the particles pass into a fluidized state, the air passing through the bed captures small particles of the product, the soaring rate of which is less than the velocity of the gas stream. When air moves inside the cylinder 10 along a spiral path in the channel 12, a stagnant zone is formed, in which material particles are deposited. Under the influence of vibration, these particles move in the direction of the y: 1 l discharge. The air through the outlet 6 of the air outlet is removed from the apparatus. The bump 13 limits the capture of particularly small particles of exhaust air. The reliable removal of powder particles from the gutter 12 is carried out by the ejector 1. The proposed apparatus allows quality processing of milk powder.
