General Techniques and Uses

    Domestic vegetable processing industry, food industry, medicine, chemical industry and other dehydration and liquid separation are substitutes, textile industry, printing and dyeing industry, such as spinning cotton, cotton, clothing and other three-foot centrifuge.

    In order to develop a special automatic dehydrator for the vegetable and food processing industry, we have collected advanced data from many countries after three to four years, and also visited and studied in Japan, the United States, and Australia. The four-wheeled prototype is the first domestic product to be successfully developed. Microcomputer control, automatic control of feeding-drying-braking-discharging throughout the whole process, blowing directly from the bucket, blowing from the bottom of the cover, closing the door, opening the door, and touching the screen to adjust the optimal time for each action. Saved 2-3 labors and reduced production costs. The machine is made of 304 stainless steel except motor and belt drive, which meets the requirements of food grade

    This machine is suitable for vegetables and food industry, such as garlic slices, shallots, onions, potatoes, ginger, green pepper, red pepper, green vegetables, cabbage, mushrooms, etc. Food, can also be used in the pharmaceutical industry, chemical industry and other products of liquid and solid products.

Fourth, the structure of the unit

    1.Feeding conveyor hoist

        Dimensions: 4100 × 800 × 2250, feed 650 × 800 × 1250, hoist plate chain width 480, transmission sprocket pitch 1½ ″ (38.1mm). Water protection board is installed at the bottom of the hoist to make return water concentrated.

    2. The three-foot centrifugal automatic water throwing machine is the main machine of the machine (see picture), which is mainly composed of motor, pulley, v-belt, main shaft, lifting shaft, bearing seat, round flange connection seat, lifting cylinder, connection seat, well It consists of a character rack, an upper and lower tripod, an outer bucket, an inner bucket, and legs. Dimensions 1800 × 1500 × 2350mm, discharge opening Φ650, 650mm high from the ground, feeding nozzle 500 × 300 × 400, falling through the feed chain to the dewatering bucket for dehydration. The swing bucket is a heart part to ensure rotation balance during processing : (1) Welding using a special mold; (2) Has passed the balance test. The size of the bucket is Φ600 × 488, the thickness is 2.5, the punching is Φ3mm, and the outer barrel is Φ800 × 610 × 3mm.

    The frame is divided into an upper tripod and a lower tripod. The tripod is made of No. 8 channel steel. The upper tripod is connected to the motor, pulley, drive shaft, vibrating internal swing bucket, lifting shaft, operating cylinder, and actuator. Imported Φ120 × 120, vibration-damping rubber spring connection, the lower tripod is grounded with three leg legs 80 × 80 × 5 square tube, three leg plates are equipped with a 10mm thick rubber plate to reduce vibration, anti-movement left on the leg plate, and anchor bolt holes Backup reinforcement.

    The discharged water flows into a mobile water tank with a filter 600 × 400 × 800 through a 3 ″ water outlet to collect and transfer to the next process.

    3.Discharge conveyor hoist

        Dimensions: 3850 × 800 × 1600. The dried material falls to the 800 × 800 feeding nozzle, which is transferred to the next process by lifting.

    4.Electrical control cabinet

        Length 800, width 460 (510 mm when the operation button handle is installed, height 1900mm).

    5. Pneumatic component control cabinet, external dimensions: 500 × 200 × 600mm

        The pneumatic components are divided into three groups, one group controls the opening and closing of the bottom cover door and three lifting cylinders, the second group controls the two lower blowing nozzles, which point to the inner liner, and the three groups control the opening and closing of the door, which points to the bottom. Sub-cylinder: seamless steel tube Φ133 × 440 × 3mm head plate δ10mm.

V. working principle

    The material from the previous process is dropped into the bucket by the feeding hopper and the conveyor hoist, and the bucket is rotated at high speed instantly. Under the action of centrifugal force, the material contained in the liquid is thrown through the hole of the drum filter plate to the shell. On the inner wall, the liquid is discharged from the water outlet after the collection, and the solid (material) remains on the rotating wall. The instantaneous rotation speed decreases by the resistance brake. When the scraper and the bottom cover are lowered, the bottom door is opened to discharge, and the material automatically falls to the outlet In the feed hopper of the material lifting conveyor, in order to quickly and simultaneously clean the residual material on the inner wall of the bucket and the bottom cover, a blow nozzle device is provided from the top to the bottom and from the circumference of the bottom cover at the same time.

    Take the next action continuously cycle. Action process: Rotating bucket rotation-feeding-water throwing-bucket slowing down brake-cylinder lowering and opening the door-discharge-blowing-cylinder raising and closing. Automatic continuous loop.

Six, precautions for operation

    1. The drum must be uniformly fed by the feeder under normal rotation. The limit of feeding is 15-25 kg. Be careful not to rotate eccentrically and damage the equipment.

    2. The centrifugal water shaker must be operated by a special person. It is not allowed to change people at will, it is not allowed to increase the limit of loading at will, and it is not allowed to plunge the material by hand.

    3. Before turning on the power, you must check whether the motor part and the connecting bolts are tight, and whether the V-belt is adjusted to an appropriate tightness.

    4. The tightening direction is in accordance with the direction indicated by the arrow.

    5. The operation procedure of the electric control cabinet must meet the requirements. The time of each process adjusted by the touch screen must be based on the time required for the material. The feeding limit is controlled by the hopper gate and the feeding time. The feeding during rotation is adjusted by the control program and the touch screen time.

    6. The operator should also read the instruction manual of the air compressor at the same time.

Installation of the automatic centrifugal water shaker

    1. The centrifuge should be fixed on the overall concrete foundation, install three anchor screws, and perform level correction.

    2. Adjusting feet are installed for feeding and discharging, and the overall level needs to be corrected during installation.

    3. The electrical control cabinet needs a safety grounding protection device.

    Because the main motor, reducer, electrical and parts of the machine are imported parts specified by the user.

    Residual current should be in accordance with European standard: IEC leakage current: 300MA-500MA

Eight, maintenance, cleaning and maintenance

    The biggest difficulty of the centrifugal automatic water thrower (dehydrator) is to separate the suspension, the corrosive solution, the cooked leafy vegetables, and various kinds of granular condensate into the holes or the wall of the bucket. The long time affects the next process, so it needs to be washed and cleaned regularly.

        1. Depending on the material, the degree of blockage is different, and the frequency of the flushing time is different. Normally, it is flushed every 3-8 hours.

        2. Normally flush and clean the incoming and outgoing materials every time. Use the air gun to blow off the relevant parts. The water pipe is connected to the outer bucket and the inner bucket, and the bottom inlet is flushed with water. If necessary, use a high-pressure water gun to align. Rinse the inner wall of the bucket.

        3. Flush all health corners according to the above before suspending holidays.

        4. Do not change the automatic operation procedure of the centrifuge at will.

        5. After one year, it must be fully maintained once, clean the rotating bearing parts, and fill with good lubricating oil.

        6. Frequently check whether the fasteners of the components of the centrifugal shaker are loose, and whether the power supply, electrical, air compressor and other parts are normal.
