What is cake dryer?

Cake dryer is a high-speed centrifugal spray dryer. It can make materials such as solutions, emulsions, suspensions, pastes, etc., become dry powdery, fine, and medium granular products through spray drying. It has high speed, high efficiency, less process, and saves manpower. Especially for heat-sensitive materials can keep the color, fragrance, and taste of the materials. The dried product has excellent quality, good fluidity and solubility, high purity, and environmental hygiene. It is conducive to improving the output and getting good economic benefits. It has a broad future in chemical, light industry, building materials, food, forestry chemical, drug, biochemical and other industries.

Working principle of cake dryer

After the air passes through the filter and heating device in the cake dryer, it enters the hot air distributor at the top of the drying chamber. The hot air passing through the hot air distributor enters the drying chamber evenly in a spiral shape, while the liquid is conveyed by the feed pump to the centrifugal atomizer installed at the top of the drying chamber. The liquid is dispersed into very small mist droplets so that the surface area of contact between the liquid and the hot air is greatly increased. The moisture is quickly evaporated in a very short time and dried into the powder or granular products, and the small liquid droplets and hot air flow down together and are collected from the bottom of the tower through the two-stage cyclone separator, and the exhaust gas is discharged from the induced draft fan to the outside world.

By using a unique heat transfer system, the cake dryer machine ensures uniformity across all heating panels. The ergonomically designed unit features swinging doors, front and rear access, and heating plates suspended from the roof to reduce the possibility of accidental spills. Hanging panels leave the floor inside the drying cabinet open for easy cleaning. cake dryer is modular in design and can accommodate capacities from kilograms to mass production. It can be used as a stand-alone unit or in a high-protection glove box.

Feature of cake dryer

a. The drying speed of cake dryer is fast, the surface area of the material liquid is greatly increased after atomization, and 95%-98% of the water can be evaporated instantly in the hot air flow, and the drying time is only a few seconds. The drying time of cake drying machine only takes a few seconds, especially suitable for the drying of heat-sensitive materials.

b. The product produced by cake dryer has good uniformity, fluidity and solubility, high product purity and good quality.

c. The production process of cake dryer is simplified and the operation control is convenient. After drying, it does not need to be crushed and screened, reducing the production process and product purity. The product particle size, bulk density and moisture can be changed within a certain It can be adjusted by changing the operating conditions within a certain range, and it is very convenient to control and manage.

Type of cake dryer

Straight tube airflow dryerThe wet material is added to the upright tube by the feeder, and the air is blown into the fin heater by the blower, heated to a certain temperature and then blown into the upright tube, the speed in the tube is determined by the size and density of the wet particles, which is generally greater than the settling speed of the particles (about 10~20m/s). The dried particles are taken out by strong airflow and sent to two parallel cyclone separators to be separated and sent out by screw conveyor, and the exhaust gas is emptied by bag filter. Due to the short residence time, for some products, it is often necessary to use a two-stage or multi-stage tandem process.
Cyclone airflow dryerThe hot airflow entrains the dried material particles into the cyclone dryer in the tangential direction and produces rotating motion along the hot wall, so that the material particles are in a state of suspended rotating motion and dried. The wall can be equipped with steam jacket according to the need. The drying process is greatly enhanced. In addition, due to the impact of particles with the wall and crushed, the contact area of the gas-solid phase increases, which also strengthens the drying process. It is especially suitable for heat-sensitive bulk granular materials with strong water repellency and not afraid of crushing. However, it is not applicable to materials with high water content, high viscosity, low melting point, easy to sublimate and explode, and easy to produce electrostatic effect.
Pulse airflow dryerAir-flow dryer is one kind of air flow dryer. During the drying operation, the diameter of the tube is reduced or enlarged alternately, so that the airflow and the particles flow at unequal speeds, and the relative speed and heat transfer area between the airflow and the particles are larger, thus strengthening the heat and mass transfer rate. In addition, the airflow velocity in the enlarged tube is greatly reduced, and the drying time is increased accordingly.

Use of cake dryer

Daily maintenance of cake dryer

a. Before starting the machine every day, check whether the power cord is safe and firm, and whether the voltage in the plant is stable.

b. The filter of the equipment should be cleaned every day and the material debris in the dust collector should be cleaned up to ensure good ventilation of the equipment so that the equipment can give full play to the best drying effect.

c. Within 1 hour after the dryer is turned on, check whether the operating parameters of each stage of the equipment (low, medium and high) are within the normal range.

Monthly maintenance of cake dryer

a. Once a month, the filter cake dryer should be given a big cleaning, first open the box cover, use a relatively soft cotton cloth, and wipe and clean all parts of the equipment.

b. Carry out a comprehensive cleaning of the fin heat exchanger of the dryer to ensure that the heat transfer effect of the equipment reaches the best state.

c. Adding the right amount of lubricant to the frequently moving parts such as fans and bearings of the equipment can reduce the wear and tear between the parts and improve the service life.

d. Some parts of the equipment that are often active and easy to fall off should be strengthened, such as electrical wiring, hinges of the box door, pipe connections, etc.

e. Check the use of the dryer belt and adjust it appropriately to ensure that the pulley is in the best working condition.

Precautions for cake dryer

The working capacity of the heat pump is related to the environment in which the heat pump dryer is located. After one year of continuous use, the heat pump, heat pump dryer unit may become dirty and its working capacity decreases, so it is necessary to carry out special equipment inspection and equipment maintenance for food drying equipment/heat pump pepper drying/food dryer. This inspection and maintenance suggest you to contact with the heat pump, heat pump dryer factory or its maintenance department users should pay attention to when using and maintaining the unit: all safety protection devices in the unit are set before leaving the factory, do not adjust.

a. When in use, it is necessary to frequently check whether the valves of the heat pump and heat pump dryer indoor and outdoor units leak normally, so as not to reduce the circulation caused by the refrigerant system and thus affect the reliability of the unit heat production and unit operation.

b. Heat pump and heat pump dryer units should be kept clean and dry with good ventilation. Regularly clean the air-side heat exchanger (2 - 3 months) to maintain a good heat exchange effect.

c. Check the working condition of each part of the unit frequently, check whether there is oil at the filling valve of the pipe joint inside the machine food drying equipment/heat pump chili drying/food drying machine, and ensure that there is no refrigerant leakage in the unit.

d. Do not pile up debris around the heat pump and heat pump dryer units to avoid blocking the import and export, and the units should be kept clean and dry with good ventilation.
