Dryfree mainly sells dehydrator, solar dryers, heat pump dryer machines and solar+heat pump dryer.

What is a large continuous food dryer

Large-scale food drying equipment, also known as mesh belt dryer, is to distribute the material to be processed through a suitable spreading mechanism, such as star distributor, swing belt, pulverizer or granulator, and distribute it on the conveyor belt. The conveyor belt passes through a channel consisting of one or several heating units. Each heating unit is equipped with an air heating and circulation system. Each channel has one or several moisture removal systems. When the conveyor belt passes, the hot air flows from the top to the top. Down or from bottom to top through the material on the conveyor belt, so that the material can be dried evenly.

The following is a brief introduction to the food dryer.

1. What is the principle of the dryer?

The mesh belt type food dryer is to spread out the raw materials in stages, composed of various indispensable parts, and put them on the conveyor belt. The conveyor belt passes through various stages to send the temperature to the stage. Some stages are equipped with gas heat supply and reincarnation devices. Each stage and device is equipped with a dehumidification device. When the raw material reaches the transfer device, the hot gas passes through the working materials on the transfer device from different directions. This has the effect of heating and drying the original material on the conveying device.

Second, what are the advantages of food dryers

1. The heating equipment that transmits electric power and band power is the material equipment of raw materials, and has various advantages of reliable quality, safety and health, and long service life.

2. The energy transmission baking equipment introduces heat into the upper part of the raw material drying device, which can take into account each end of the raw material in the device, and the temperature is evenly distributed. (Experiment at the edge of the conveyor).

3. The amount of energy delivered is honest and reliable, facing the public, can save power resources, the size of the energy power is visible, the price is fair, the price difference is reasonable, and the factory can purchase with confidence.

4. Reliable materials for appliance packaging, the shape of the appliance is exquisite, less rust, no abrupt corners, easy to use, low energy consumption, high output, no waste of resources, and has been recognized by the public.

5. Convenient operation: It is controlled by electronic products, which can control the temperature, power, and turn over the raw materials. Easy to operate, the factory produces good tools in large quantities and can be monitored electronically.

6. Follow-up help: If there is a problem in the production of the machine, the buyer can contact the seller in time to obtain feedback. Since the food dryer has such advantages, how should we choose the food dryer? Different food dryers have their specific scope of application. If the type is not selected properly, it will increase the purchase cost, and there may be a series of problems such as low efficiency, high energy consumption, and poor product quality.

The following are the general principles for the selection of dryers provided by Dryfree:

1. Saving investment: the drying device that accomplishes the same function sometimes has a disparity in cost, so the lower one should be selected.

2. High drying rate: the food dryer is only concerned with the drying rate. During convection drying, the materials are highly dispersed in

In hot air, the critical moisture content is low, and the drying speed is fast, and the same is convection drying. The critical moisture content is different for different drying methods, so the drying rate is also different.

3. Applicability: The food dryer first needs to be suitable for specific materials and meet the basic requirements for the drying of materials, including good processing of materials (feeding, transportation, fluidization, dispersion, heat transfer, discharge, etc.) ), And can meet the basic requirements of processing capacity, dehydration capacity, product quality and other aspects.

4. Low operating costs: equipment depreciation, energy consumption, labor costs, maintenance costs, spare parts costs, etc. The operating costs should be as low as possible.

5. Low energy consumption: different drying methods have different energy consumption indexes. In general, the thermal efficiency of conductive drying can be five losses in theory, and convection drying can only be about 70%.

6. The food dryer preferentially selects the drying device with simple structure, sufficient supply of spare parts, high reliability and long service life.
