The candle filter has compact structure, which is made of 1Cr18Ni9Ti high-quality stainless steel by cold processing. The pump body is connected with the motor as a whole. It has the advantages of beautiful appearance, small volume, light weight, corrosion resistance, easy operation and maintenance. It can transport all kinds of wine, soda, milk, soy sauce, vinegar, edible vegetable oil, medicine, chemical industry, textile liquid, etc. and can be used with the filter. Candle filter can automatically regenerate the filter elements without stopping the system. It has the characteristics of full-automatic, no shutdown, less manual cleaning and no need to replace the filter elements. It has been widely used in continuous operation production, high-risk operation environment, and occasions where the impurities are sticky and not suitable for the use of ordinary metal filter elements. Candle filter adopts compound structure, has wide application field and good filtering effect. It can realize complete filtration at one time. The filter cake can be washed and dried to obtain great economic benefits.


Features of candle filter:

1. A uniform filter layer is formed on the surface of the stainless steel support ring by the filter aid, so that the filter aid can be used more effectively;

2. With better liquid characteristics, each filter rod is a separate liquid flow channel, which can double the filtration capacity of the traditional horizontal filter;

3. The candle filter can filter for a long time, making the filtering process more economical. After backwashing the filter barrel with the main pump, it can be put into use again;

4. The new type of ring buckle is adopted to make the disassembly and assembly faster and work efficiency higher;

5. Beautiful appearance, movable, convenient maintenance, few wearing parts, each part can be disassembled, and parts can be replaced quickly;


Start up steps of candle filter:

First, open the water inlet and water production valves. After the equipment starts to enter the water, it is necessary to open the air exhaust valve to discharge the gas in the tank. Then close the air exhaust valve for normal water production. When the inlet pressure is greater than 0.1MPa of the water production pressure, the equipment needs to be backwashed. After the backwashing, it is required to conduct the front row.

1) Candle filter equipment is generally used together, but each set of equipment can choose its own match, the key is to adjust the flow, pressure, pump performance, to match.

2) Before using the candle filter, safety inspection shall be carried out, such as whether the accessories and sealing rings are complete and damaged. Ensure that all functions of the air filter operate normally when it is used.

3) After using the candle filter, it is necessary to clean the filter element and shell, and at the same time, the filtrate in the equipment must be given light, and then stored to avoid equipment pollution caused by the next use.

4) When washing the filter element, it must be recoiled with sterile water. The flushing process is to pour sterile water in the opposite direction along the original outlet and open the drain outlet.

5) If the equipment is brand-new, the filter element shall be packed in plastic bags. Do not tear the plastic packaging before use. Generally, the higher filter element shall be sterilized by high temperature steam after installation.

6) The brand new candle filter must be cleaned with detergent, sterilized and disinfected with high temperature steam after cleaning to avoid pollution.


Candle filter is a kind of multi-purpose filtration equipment, which introduces and digests the winding elastic filter technology produced in Germany and combines with China's national conditions. It is suitable for filtration of beer, rice wine, all kinds of drinks, condiments and other liquid media. The candle filter adopts imported pneumatic valve for full automatic control, Siemens PLC and color touch screen for linkage control. It has good mechanical seal, long service life, can bear high pressure, can prolong working time, can wash forward and backward, and can recover residual liquid after filtration.
