DWT multi-layer (dehydrated vegetable) belt dryer

Application of dehydration and drying equipment:

It can meet the drying and large-scale continuous production of vegetable materials such as roots, stems, leaves, strips, blocks, flakes, and large particles, while maximizing the retention of the nutritional content and color of the product.

Typical dry materials include garlic slices, pumpkin, carrots, konjac, yam, bamboo shoots, horseradish, onions, apples, etc.

Drying process and working principle:

The interior of the host is composed of 5-7 layers of mesh belts, which are supported by the support rod below. The support rod is driven by chains on both sides, and there is a baffle on the top of the chain to prevent materials from falling into the middle of the track. The mesh belt is fixed on the support rod. The clean hot air exchanged from the steam or hot air stove is sent to the bottom of the dryer and first passes through the bottom layer of the mesh belt to exchange heat with the dry material and remove some moisture. It then passes through each layer of mesh belt layer by layer, forming a counter current heat exchange with the material. After reaching the upper layer and exchanging heat with the wet material, the humid air approaches saturation and enters the dehumidification fan for discharge. Due to the counter current form of heat and mass exchange, the heat is reused multiple times, and the exhaust temperature is extremely low. This not only reduces the power consumption of multiple fan cycles required for ordinary multi-layer belt drying, but also avoids the large heat loss of ordinary belt drying. It is a new type of drying equipment that is efficient, energy-saving, and low investment. Currently, it has been widely used in multiple industries, including dehydrated vegetables.

The drying area, air pressure, air volume, drying temperature, and mesh belt speed can all be adjusted to meet the characteristics and quality requirements of vegetables.

Different water processes and necessary auxiliary equipment can be used according to the different characteristics of vegetables.
