[0018] Furthermore, a novel energy-saving and environmentally friendly fruit and vegetable drying machine control method comprises the following steps:

[0019] Step 1: Place the water receiving box on the material trolley until the rear end of the water receiving box is in close contact with the positioning plate, then turn the rotating plate, and the rotating plate rotates on the fixed plate through the rotating shaft. After the rotating plate rotates to the bridging plate, the rotating plate can limit the water receiving box. When placing fruits, vegetables or Chinese medicinal materials on the material trolley, water stains will drip downwards, and the water stains will fall into the water receiving box through the fixed bucket drainage. By setting a water receiving component, the water stains dripping from the fruits, vegetables or Chinese medicinal materials placed on the material trolley can be collected to prevent the water stains from polluting the interior of the drying room. By setting a filtering component, the water stains fall into the water receiving box and are filtered through the filter net. The water stains contain impurities or impurities of fruits, vegetables and Chinese medicinal materials. After removing the water receiving box from the material trolley, the vertical rod is used to pull the card block to move upward in the vertical slot. The card block can take the filter net out of the water receiving box, so that the filter net can be cleaned. By setting a filtering component, the water stains falling into the water receiving box can be filtered;

[0020] Step 2: Dust is generated when fuel is added to the feed hopper. The fan is turned on. The fan sucks the smoke and dust into the dust reduction box through the dust inlet hopper and the fixed pipe. The dust-containing air is filtered through the sand and gravel layer and the activated carbon layer and then discharged from the dust reduction box through the exhaust pipe. The dust reduction component can be set to reduce the dust generated when the fuel is added to the feed hopper, thereby reducing the pollution of the dust to the air. The installation component is set to unscrew the fixing bolts from the fixing holes, and the installation plate can be taken out of the installation port. After that, the sand and gravel layer and the activated carbon layer can be taken out of the dust reduction box through the installation port. The installation component is set to facilitate the disassembly and replacement of the sand and gravel layer and the activated carbon layer.

[0021] Step 3: Turn on the motor to drive the main roller to rotate clockwise, and the main roller drives the auxiliary roller to rotate counterclockwise through the main gear and the auxiliary gear. When the fuel is put into the feed hopper, the fuel is guided into between the main roller and the auxiliary roller through the guide seat. The main roller and the auxiliary roller rotate towards each other and crush the larger fuel through the crushing teeth. The crushed fuel enters the built-in hot air furnace. By setting the crushing component, the larger fuel added to the feed hopper can be crushed to avoid blockage in the feed hopper caused by large fuel.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. The present invention sets a water receiving assembly, places a water receiving box on the material trolley, until the rear end of the water receiving box is in close contact with the positioning plate, then moves the rotating plate, and the rotating plate rotates on the fixed plate through the rotating shaft. After the rotating plate rotates to the bridging plate, the rotating plate can limit the water receiving box. When fruits, vegetables or Chinese medicinal materials are placed on the material trolley, water stains will drip downward, and the water stains will fall into the water receiving box through the fixed bucket. By setting the water receiving assembly, the water stains dripping from the fruits, vegetables or Chinese medicinal materials placed on the material trolley can be collected to prevent the water stains from polluting the inside of the drying room.

[0024] 2. The present invention sets a dust reduction component. When adding fuel into the feed hopper, dust is generated. The fan is turned on and the smoke is sucked into the dust reduction box through the dust inlet hopper and the fixed pipe. The dust-containing air is filtered through the sand and gravel layer and the activated carbon layer and then discharged from the dust reduction box through the exhaust pipe. By setting the dust reduction component, the dust generated when adding fuel into the feed hopper can be treated to reduce dust pollution to the air.

[0025] 3. The present invention sets a crushing assembly, starts the motor to drive the main roller to rotate clockwise, and the main roller drives the auxiliary roller to rotate counterclockwise through the main gear and the auxiliary gear. When the fuel is put into the feed hopper, the fuel is guided into between the main roller and the auxiliary roller through the guide seat, and the main roller and the auxiliary roller rotate in opposite directions to crush the larger fuel through the crushing teeth. The crushed fuel enters the built-in hot air furnace. By setting the crushing assembly, the larger fuel added to the feed hopper can be crushed to avoid blockage in the feed hopper caused by the larger fuel. BRIEF DESCRIPTION OF THE DRAWINGS
