    After Drying

Coconut coir pith is a waste material generated from the husks of coconut (Cocos nucifera L.) during the extraction of coir fiber. Coir pith is an excellent growth medium due to the specific quality characteristics of high water retention ability due to the porosity of the cell structure and the fertility as it contains macro and micro nutrients. At present there is an increasing demand for coir pith as a sound alternative to sphagnum peat especially in soilless growth medium for containerized crop production. Drying plays a major role in manufacturing of coir pith products.

Coir pith is a porous agricultural material, obtaining as by product of coir fiber industry. Improper drying causes several negative effects on the structure of this biological material and the main problems can be identified as loss of rehydration ability, case hardening, color changes, shrinkage of cells, etc. Since the drying temperature is a critical parameter, ZJN have dedicated many years on exploring how to keep the coconut coir pith nature during the drying process.

ZJN Drying Equipment for coconut shell is used for drying coconut shell, coconut husk, coconut palm sludge, shredded coconut etc. It is three cylinders rotary multi-loop dryer. Material directly contact with hot air and heated evenly in the cylinder so that moisture is instantly reduced. With high heat utilization, it can greatly improve the production efficiency.

ZJN rotary drum dryer biggest advantages is hot air distribution system to adjust the hot air volume and temperature inside the dryer to keep the coir pith fiber quality.

The wet material is conveyed by the belt conveyor or bucket elevator to the hopper, and then being fed into the inner cylinder (called first level dryer) through the hopper. With the rotation of the cylinder, the material is subjected to gravity to the lower end and pass the rotating rake device which will disperse the wet and sticky coconut shell into small size. Thus hot air contact area will be increased and the material surface will be quickly dried. It well prevents material from sticking to the cylinder wall. The moisture content instantly reduce during forward movement and enter into the medium drum (called second level dryer). In this level, material forwarding trend opposite with hot air trend, which ensures the bound water will be dry. With a rapid drying in the outer cylinder (called the third level dryer), the wetter material moves slower, and dryer moves faster. At last material will be thoroughly and uniformly reach to the drying purpose, and being discharged through belt conveyor or screw conveyor.

There are lifting boards with different angels and distances on the wall. They play a role to take the material and spread it out so as to increase the hot air contact area and improve the drying rate and promote the material forwarding speed. The steam vapor evaporated from each cylinder is discharged directly from the end of current cylinder to prevent it from being absorbed again.

The dry coconut shell can be used for animal feed, fillers for mattress, sofa and seats. Coconut shell dryer can also be used for corn straw drying, soybean straw drying, cotton straw drying, wheat straw drying, sorghum straw drying, wood drying, shaving drying, palm leaf drying and other agricultural cellulose materials drying.

Composition of ZJN dryer

Brief Introduction Of Coconut Coir Dryer

Grains and dregs are the surplus by-products produced in the production process of food or agricultural products processing, wine making and other industries, which are rich in material resources. According to the data statistics, the annual production of dregs in China is on the rise. If it is not handled in time, it is not only easy to ferment, rot, stink, breed mosquitoes, cause serious pollution to the environment, but also increase the production cost of enterprises. However, due to the rich organic matter, nitrogen, phosphorus, potassium and other mineral trace elements needed for crop production, as well as a large number of carbohydrates, crude protein, crude fat and crude fiber, it is very suitable for livestock feed.

The dregs dryer can quickly dry the materials with moisture content of about 80% to about 10%, greatly reducing the moisture content in the materials, reducing the volume of materials, and facilitating the subsequent transportation and storage. The materials dried by the dregs dryer can be further recycled, which can not only turn industrial waste into treasure, but also reduce environmental pollution, and improve the added value of dregs products

Working Principle Of Coconut Coir Dryer

Working principle of ZJN dryer

The structure design of the dregs dryer is reasonable, which is mainly composed of hot blast stove, feeding device, dryer body, discharging device, induced draft fan, dust removal equipment, power distribution cabinet, etc.

Its technological process: hot blast stove is the place to produce heat energy. The fuel is added into the hot blast stove to produce high-temperature heat medium through combustion, which provides continuous and stable heat for the main body of the dryer. Then, the feeding device (belt conveyor, seal scraper conveyor or screw conveyor) evenly and continuously sends the materials into the dryer. The heat exchange between the material and the high-temperature heat medium is carried out inside the cylinder, so that the moisture in the material is evaporated, and the material changes from high humidity and high viscosity to non humidity and non viscosity. The materials meeting the drying requirements are transported out through the discharging device for unified packaging and loading. The flue gas, dust and other gases generated in the drying process are transported to the dust removal equipment through the induced draft fan for purification, filtration and dust reduction, so as to achieve the gas emission standard. The whole drying production line is integrated to complete the drying of materials.

Exhaust Gas Emission Collecting System

ZJN Scrubber

Scrubber

Scrubber systems (e.g. chemical scrubbers, gas scrubbers) are a diverse group of air pollution control devices that can be used to remove some particulates and/or gases from industrial exhaust streams.

The exhaust gases of combustion may contain substances considered harmful to the environment, and the scrubber may remove or neutralize those. A wet scrubber is used for cleaning air, fuel gas or other gases of various pollutants and dust particles. Wet scrubbing works via the contact of target compounds or particulate matter with the scrubbing solution. Solutions may simply be water (for dust) or solutions of reagents that specifically target certain compounds.

ZJN Cyclone Dust Collector

Cyclone Dust Collector

Centrifugal cyclone dust collector, the dust will be separated and recovered in the drying system, through the dry tail gas dust purification device of a cyclone dust collector, suitable for high dust concentration, large dust particles of exhaust gas dust removal operations, the dust collector has a simple structure, stable and reliable operation, long service life, and other characteristics.

ZJN Baghouse

Baghouse

A bag house, also known as a bag house filter, bag filter, or fabric filter is an air pollution control device and dust collector that removes particulates or gas released from commercial processes out of the air.

Most baghouses use long, cylindrical bags (or tubes) made of woven or felted fabric as a filter medium. For applications where there is relatively low dust loading and gas temperatures are 250 °F (121 °C) or less, pleated, non woven cartridges are sometimes used as filtering media instead of bags.

Bag houses are very efficient particulate collectors because of the dust cake formed on the surface of the bags. The fabric provides a surface on which dust collects through the following four mechanisms:

Inertial collection – Dust particles strike the fibers placed perpendicular to the gas-flow direction instead of changing direction with the gas stream.

Interception – Particles that do not cross the fluid streamlines come in contact with fibers because of the fiber size.

Brownian movement – Sub micrometre particles are diffused, increasing the probability of contact between the particles and collecting surfaces.

Electrostatic forces – The presence of an electrostatic charge on the particles and the filter can increase dust capture.

A combination of these mechanisms results in formation of the dust cake on the filter, which eventually increases the resistance to gas flow. The filter must be cleaned periodically.
