Equipment dimensions: 9900mm (length) × 1250mm (width) × 1600mm (height)

The appearance is computer white.

Main parameters of the equipment

The total length of the equipment is 9.9m, including the feeding section 1.0m, the inlet insulation section 0.2m, the heating section 8.0m (heating section is divided into 4 sections, the length is 2.0m, 4 sections are independently controlled), the cooling section is 0.2m, The lowering section is 0.90m; the upper feeding section and the heating section (four sections in total), and the cooling lowering section are divided into six independent sections, which are spliced on site. I

The outer casing of the equipment is made of cold-rolled steel plate and sprayed, and the inner liner is made of t1.0mm#304 stainless steel plate. It has good corrosion resistance, heat resistance, strength and mechanical properties, ensuring the baking area. The cleanliness of the lower box frame is 40*40 iron square welding, high temperature spray treatment; 3 inch black low center of gravity universal wheel is installed at the bottom of each frame, the bearing performance is good, and the whole machine is convenient to move;

Adopt IR IR lamp heating mode: Infrared lamp power 1KW/branch, arrangement: 9 segments in each section of the heating zone, and the infrared heating pipe is evenly arranged in the vertical mesh belt conveying direction.

Conveyor coffee Teflon mesh belt, imported raw materials, anti-aging, long service life, easy to clean, resistant to various strong acid and alkali corrosion, chemical resistance, non-toxic, breathable, reduce heat loss, improve drying efficiency ;

The transmission motor adopts Taiwan Aideli geared motor and Taiwan Delta inverter, the conveying is stable and the speed is infinitely adjustable;

Insulation material is made of high quality 120K aluminum silicate cotton, using advanced heat insulation technology, double insulation, resistance to heat conduction, good thermal insulation performance, minimizing heat loss, thus achieving energy saving; heating zone 6 has insulation layer The thickness of the insulation layer is 150mm (both sides of the temperature zone) / 100mm (top and end of the temperature zone); the temperature of the outer surface of the equipment is within room temperature + 10 °C.

Adopt PLC control + human-machine interface touch screen integrated control mode, a variety of drying methods: infrared radiation + hot air circulation,
