Roll dryer  working principle:

1.Material to be dried enters the dryer, and as the dryer rotates, the material is lifted up by a series of internal fins lining the inner wall of the dryer.

2.When the material gets high enough to roll back off the fins, it falls back down to the bottom of the dryer, passing through the hot gas stream as it falls.

3.This gas stream can either be moving toward the discharge end from the feed end , or toward the feed end from the discharge end.

4.The gas stream can be made up of a mixture of air and combustion gases from a burner, in which case the dryer is called a direct heated dryer.

5.Alternatively, the gas stream may consist of air or another (sometimes inert) gas that is preheated.

6.When the gas stream is preheated by some means where burner combustion gases do not enter the dryer, the dryer known as an indirect-heated type.

7.Often, indirect heated dryers are used when product contamination is a concern.

Roll dryer  features:

1.Air heating system is able to allow highly efficient removal of water from fresh harvested forage, and the maximum durability of dehydrated forage.

2.Non-pollution to the target materials guarantees minimal loss of their color,favor,and mutritional ingredients;

3.smoke collector working with the air heating system adopts water-recled wet-type collecting method,and ensure the exhausted gas to satify the environmental protection requirement as well as the lowest water consumption.

 

2.New Technology Description:

Five-Column Three-Effect Distillation Process

 

Our company designs and manufactures latestFive-Column Three-Effect Distillation equipment.This new process is promoted on the basis of traditional five-column differential-pressure column and mainly used for super-fine alcohol production.

The key of this process is the heating methods,the steam heats one column directly and transfers theheat to other 4 columnsto achieve three-effect thermal coupling and energy-saving effects.

In terms of electricityefficiency, it can save 50% electricity and avoid the repairing of circulating pumps and also extend the working life of there-boilers.

Double-Mash-Column Three-Effect Distillation Process

 

This process applies to the production of general-grade alcohol& fuel ethanol, and it was awarded Chinese national patent, it is the onlysuccessfulapplicationof double mash column & three-effect in the world,which produces general-grade alcohol.

This process is composed by mash column, rectification column and composite column. The composite column functions as mash column and rectification column.

The key of this process is the heating methods: the steam heats one column directly and transfers the heat to other 2 columns to achieve three-effect thermal coupling and energy-saving effects.

The advantage of this process is energy-saving;it saves over 40% steam

Q:What are the characteristics of the drum dryer?
The main body of the rotary drum dryer is a slightly tilted and rotatable drum, and the wet material is fed from one end thereof and passes through the inside of the drum and is dried in contact with the hot air or the heated wall in the cylinder. , Chemical industry, metallurgy, building materials and other industries have a wide range of applications. Rotary drum drying and other drying equipment compared to the production capacity, continuous operation and simple structure, easy operation and less trouble, low maintenance costs
Q:How to solve the dryer a series of failures
The dew point reading can help to find some problems, so the dry air dew point value should be monitored throughout the drying process. Dryer normal operation of the dew point reading should be 20of ~ 50of within a straight line, of course, the replacement of the dryer caused by small fluctuations are normal. If the dryer is operating normally, the dew point at the dry air inlet should be at least 30of lower than the dew point at the return air outlet.
Q:How to choose the right drying equipment and drying technology
In determining the drying process, it is of vital importance to identify the drying properties of the material.
Q:What are the basic types of common drying equipment?
(4) hollow paddle dryer (leaf dryer) hollow paddle dry dryer, also known as leaf dryer, mainly by the jacket with the W-shaped shell and two hollow blade shaft and transmission components. A hollow blade is arranged on the shaft and a rotary joint with a heat medium inlet is provided at the shaft end. The heat required to dry the moisture is conducted to the material by the inner wall of the W-shaped groove with the jacket and the hollow leaf wall.
Q:What is the best drying equipment?
Through the filter to make hot air purification, and then by the left shunt plate to the layers, so that the average hot air through each layer of dry material.
Q:What are the types of drying equipment?
the drying medium, the thermal efficiency is high, the product is not polluted, but the drying capacity by the metal wall heat transfer area limit, the structure is also more complex, often in vacuum operation; radiation dryer is the use of various radiation Emitting a certain wavelength range of electromagnetic waves, the wet material surface is selectively absorbed into heat after the dry; dielectric dryer is the use of high-frequency electric field effect, so that the wet material inside the thermal effect of drying
Q:What is a combination of drying equipment?
In this way, the drying rate can be increased, and a drying apparatus having a small volume and a high thermal efficiency can be obtained.
Q:The development prospects of the dryer
performance, the use of compact heat exchangers, such as plate fin heat exchangers, is promising. (The current difficulties may still be in terms of price). Promotion of the use of green ring-type refrigerant R134a, including cold and dry machines, including all the direction of development of refrigeration equipment, technically there is no insurmountable obstacles. But this is a great social engineering, an industry, a separate action of a business in addition to some commercial publicity significance, the overall goal of the macro is not much practical effect. In the final analysis, this is a government action, the need for the introduction of policies by the state to define a unified time limit.
Q:What are the common types of dryers?
The belt dryer consists of a number of individual unit segments, each of which includes a circulating fan, a heating device, a separate or common fresh air extraction system and an exhaust gas extraction system. The amount of drying medium, temperature, humidity and exhaust cycle
Q:The working principle of belt dryer
Drying process is a hot air flow through the material layer, complete the process of heat and mass transfer, the upper cavity connected by the duct and the fan inlet. Most of the gas circulation, part of the lower temperature of the larger moisture content of the gas as exhaust gas through the drainage tube, regulating valve, drain fan discharge. The next cycle of the unit, the fan out of the wind into the upper cavity, down through the heat exchanger heating, through the material layer into the lower chamber, the lower chamber by the side duct and return air duct connected to the fan, most of the gas circulation, Part of the discharge. Up and down the cycle unit according to user needs can be flexible equipment, the number of units can also be selected according to need.
