Changzhou ZHENXING Environmental Technology Engineering Co., Ltd.,this is Drying Equipment manufacture. We are specialized in development, manufacturing, and installation of dryers, mixers, granulators, grinders, conveyors, sieve and etc。

1.Fine droplets are dried in the drying camber by supplying hot air through the inlet.
2.The surface of the liquid drop is dried immediately to form a tough shell.
3.Further the liquid inside must escape by diffusing through the shell at a particular rate.
4.At the same time heat transfer from outside to inside takes place at a rate greater than liquid diffusion rate.
5.As a result heat inside mounts up which allows the liquid to evaporates at faster rate.
6.This tendency of a liquid leadsto rise in the internal pressure which causes the droplets to swell.
7.The shells thickness decreases where as permeability for vapour increases.
8.If the shell is neither elastic nor permeable it ruputur and the internal pressure escapes.
9.The temperature of the air is adjusted in such a way that the droplets should be compeletly dried before reaching the walls of the drying chamber.
10.The products should not be over heated at the same time.

1.Spray dryer can be used for drying of ny substances both in solution or in suspension.
2.Spray dryer are very useful for the drying of thermolabile substances.
3.Citric acid, borax, sodium phosphate, hexamine, gelatine and extracts are dried by a spray dryer.
4.The suspensions of starch, barium sulphate and calcium phosphate are also dried by the spray dryer.
5.Milk, soap and detergents too are dried by a spray dryer.

Design and production
We solicit buyers opinions widely at the design and production stage of equipment; especially at the stage of plan and elevation arrangement, we give full consideration to buyers’ site conditions and public engineering conditions, and pay concurrent attention to the optimum combination when assuring the quality of equipment.
Installation and commissioning
After the equipment is delivered to buyers factory, we will dispatch full-time technical personnel to instruct buyers’ installation and to take charge of commissioning until normal use of the equipment.
Training
Before buyers use our equipment normally, our commissioning personnel will organize buyers’ relevant personnel to accept training, which covers the maintenance and care of equipment, timely repair of common faults, and procedures for operation of equipment.
Warranty
We provide one-year warranty for our equipment. For damage of equipment arising from non-artificial factors within the warranty period, we will provide repair service for free; and for damage of equipment arising from artificial factors, we will provide repair service in time and collect corresponding cost.
Maintenance and period
For damage of equipment after expiration of warranty period, we will provide on-site repair service within 24h/48h for enterprises inside/outside the province after receiving buyers’ notification. The service provided after expiration of warranty period is fee-based, and flat cost will be collected each time when the service is provided.
