LPG spray dryer for instant coffee

Product Introduction

Equipped with a centrifugal atomizer, centrifugal spray drying tower is one of the most widely used dryer in industrial production. By adding material liquid to the high-speed rotating spray tray , the liquid is flung into droplets after drying in the drying chamber subjected to centrifugal force.

Working Principle

Feed pump sends pump water reducing agent solution to the high-speed centrifugal atomizer in the middle of the drying tower by using high-speed rotating centrifugal force, the material liquid to spray fine droplets. Approved by the heat source of hot air, heating points after reasonable ventilation, win into the drying tower. Droplets are fully mixed with a hot air drying tower, for heat and mass transfer in quickly,in a very short time be dry powder products, grain size larger products from the dry bottom, smaller particle size product with hot air into the cyclone dust collector, separation of products by the discharge valve discharge, via water containing a small amount of dust exhaust dust after emptying.

Functions and features

(1) High drying speed: after spraying of the material, the surface area of the material will be increased greatly.

(2) Concurrent flow type of spray drying is adopted to let liquid drops flow in the same direction as the hot air.

(3) This type of machine is widely used. Hot or cool air dry can be chosen according to the specialty of material.

(4) As the material is dried momentarily, the product keeps the ball shape in good disparity, fluidity, and solubility.

(5) Manufacturing process is simplified and operation is easy to be controlled.

(6) In order to keep the material clear and prolong the service life of the equipment, stainless steel is chosen to construct the parts in contact with the material.
