Grapes contain 0.5% plant fiber, as well as potassium chloride, iron, and phosphorus. The grape juice made also contains a large amount of sugar that is easy to digest and absorb. The carbohydrate content is as high as 16%, with the majority being glucose. Grape juice is often used to ferment and make wine, brandy, or whiskey. In the brewing industry, grape juice is an essential product.

HydroPro PTJ Self-cleaning Filter Guide

After the production of wine, it is necessary to manually filter the residue in the wine. The existing filtering method is to pour unfiltered grape juice onto a filter screen, allowing the filter to filter grape residue.

Due to prolonged use of the filter, it can cause blockage, which in turn affects the normal use of grape juice filtration. Replacing the filter with a new one would be a waste of time.

The filtered residue on the filter contains a small amount of grape juice, and directly discarding it will cause waste of grape juice. We have designed a self-cleaning filter for wine production to address the above issues.

During the filtration process, the accumulated filter residue on the filter can be cleaned. This ensures that the filter is not clogged and improves the efficiency of wine filtration. During the filtration process, the cleaned filter residue can be squeezed and filtered again. Allow the wine remaining in the filter residue to be filtered again. Reduced waste caused by cleaning filter residue.
In summary, it can effectively clean up the residue accumulated on the filter screen. Ensure that the filter screen does not slow down due to blockage. It also effectively utilizes the cleaned filter residue for re-filtration, reducing the waste of grape juice raw materials.

Traditional self-cleaning filters often experience clogging of the filter element during use. Generally, manual or automatic control is used to backwash the filter element using system water pressure. In severe cases, it is necessary to manually remove the filter element for external cleaning. This not only wastes time and manpower but also brings many inconveniences to the water system. For this, we provide an ultrasonic automatic cleaning filter.


  • Including a deceleration drive motor, multiple filter elements, and multiple ultrasonic vibration plates.
  • Water inlet, filter flushing pipe, and spherical tank.
  • Water outlet, tray, backwash drainage pipe, and control switch.
  • The deceleration drive motor is located at the upper end of the spherical tank. The output shaft of the deceleration drive motor extends into the interior of the spherical tank. Connect to the middle of the filter flushing pipe. The deceleration drive motor drives the filter flushing pipe to rotate together.
  • There are two drain outlets on the filter flushing pipe.
  • The head end of the backwash drainage pipe is connected to the filter flushing pipe through a bearing.
  • The end of the backwash drainage pipe passes through the bottom of the spherical tank and extends to the outside of the tank.
  • There is an electromagnetic valve at the end of the backwash drainage pipe. The tray is connected to the output shaft of the deceleration drive motor through bearings.
  • There are multiple through holes on the tray. Multiple filter elements are connected in the through-holes of the tray.
  • When the filter flushing pipe rotates, the two drain outlets of the filter flushing pipe correspond to the through holes on the tray.
  • The spherical tanks on both sides of the tray have water outlets and water inlets respectively.
  • There is a control switch on the outside of the spherical tank.
  • The deceleration drive motor, multiple ultrasonic vibration plates, and solenoid valves are respectively connected in parallel with the control switch through wires.
  • The filter flushing pipe is a C-shaped pipe.


Further ensuring the fine cleaning process of the filter element. The secondary cleaning of the ultrasonic vibration plate improves the cleaning effect of the filter element. The filter operates more stably.
The addition of ultrasonic vibration plates can improve the automation level of self-cleaning filters. Maximizing manpower savings and reducing energy waste caused by frequent backwashing.
