(一)fine filter sheets Description Reference
 

This product is only suitable for use on a fine filter. The filtrate was first with a diatomaceous earth filter body coarse filtration or separation from the machine too. Otherwise, easy to plug the filter plate.



Filter ago
Install filter plates: Due to the fine filter sheets containing diatomaceous earth and other ingredients, easy to damage, cardboard care should be taken gently, while avoiding friction between the cardboard from the skin. Pre-installation check the filter gasket is intact, whether the dislocation between the filter frame and filter separators and sieve box whether a prominent position, if any should be replaced, repair; former board installation should pay attention mesh side scored liquid outflow side, above the company trademark stamping. Filter sheets must go beyond about 5-6 mm around the edges of the frame, the inlet valve opens after installation cardboard imported water, no pressure for 10 minutes, the purpose is to wet cardboard. Then take the cardboard clamp exhaust water, the water temperature at 85 ℃, time is 10-15 minutes.


Filtration
Coarse filter in good condition, the flow rate should be controlled at 300 liters / hour meters. To control the flow rate, pressure and avoid shock, do not suddenly change the flow rate and avoid mixing air. During filtration resistance increased when the filter is completed, the filter differential pressure not exceeding 3.0 atm. (Coated fine filter plate) complete regeneration of the filter backwash water can exit through the frame filter to import diagonal inverted flushing, hot water temperature 40 ° C-45 ° C countercurrent into the room for 10 minutes about.


Sterilization regeneration
Diagonal circulation with temperature 85 ℃ -90 ℃ hot water along the filtration direction, for about 20 minutes. Not leave any dead ends, it can also be used steam bacteria. Plates should be cooled after sterilization with alcohol after use with warm, cardboard sterilization after washing can be used repeatedly.


Cardboard processing
Our filter sheets for the natural environment-friendly raw materials, unused filter sheets may be reproduced with other paper, like, can also be according to other household waste. After filtration using cardboard basis having local environmental protection and waste disposal regulations.


Storage and shelf life
The filter sheets during transport and storage process to avoid squeezing, impact and odor pollution. It requires transportation, storage environment dry, no dust, no smell, storage environment should be well ventilated, room temperature can. Not allowed to close or volatile chemicals, oils or other goods was particularly strong taste of stored together.


(二)Filter support plate Description Reference
 

Filter preparation work
Cardboard should be taken gently, so as not to rub against each other from the skin. Installation should pay attention to distinguish between the liquid surface and the inflow outflow surface, the rough surface of the cardboard surface inflow and outflow face a stamping of the company trademark. The new board sufficiently wetted with water, the rinsing time is not less than 15 minutes, a flow rate of 1.5-2 times the normal speed of the filter. Purpose is to make cardboard full infiltration and moderate expansion of cardboard inside the exclusion of air, to achieve good adsorption effect. To prevent bad Ge cardboard, dislocation and check whether the filter box sieve Are there protruding parts, such as there are, after trimming and separator used between the filter box.


Precoated:
Press twice to coat the way I painted, pre-coated loop through Celite slurry so that a layer of soil deposited on the filter bed formed the basis of cardboard, in order to facilitate the clear filtrate, through the process of pre-coated paperboard can be prevented from being in the filtrate space yeast and other sticky substances clogging, long life, but also conducive to the end of the cardboard filter cleaning. According to the manufacturers filtrate circumstances, appropriate adjustments to coarse, fine soil should be applied and the ratio of the actual situation and the technical requirements precoating. It painted slightly longer cycle time as possible, in order to form a solid filter plate, a filter layer having a uniform thickness.


Add filter:
The filter machine performance, diatomaceous earth (activated charcoal) and filtrate quality conditions (high and low filtrate is the body, the fermentation of yeast content, etc.), and the proportion of Celite reasonable adjustments add addition amount filtration rate reasonable adjustments to achieve the best filtering effect . At first filter within half an hour, add the appropriate amount of increase, to further secure the filter layer. In the filtering process, it should be kept steady pressure, prevent improper operation, resulting coating off, affecting the filtering effect. Cardboard amount of 0.01-0.02 m / tons, but due to the requirements of users of the products, the kind of body filtrate, filtration pressure is different, this data is for reference only.


Washing, regeneration:
After filtration with a wooden or plastic utensil to clear the filter cake (not to damage the cardboard), and then use soft water, carefully rinse the filter sheets contain yeast and protein retentate layer of diatomaceous earth, washing the filter in the same direction, heated 70 ℃ water at normal speed through the filter sheets, so that all parts of the filter are arriving.


Sterilization:
Cardboard sterilization should be carried out as soon as possible after the end of the filter, to avoid the propagation of microorganisms, to prepare for the next reuse. Sterilizing filtration direction using the same 85 ℃ -90 ℃ hot water, steam sterilization may also be performed, at a temperature of 100 ℃ -110 ℃, for 20 minutes, each filter plate is normally 15-20 times can be used repeatedly.


Cardboard processing
Our filter sheets for the natural environment-friendly raw materials, unused filter sheets can be regenerated like other paper, also in accordance with other household waste. After filtration using cardboard basis having local environmental protection and waste disposal regulations.


Transport, storage and shelf life
The filter is a cardboard adsorptive fibers, so the transport and storage process to avoid contamination squeeze pressure, collision and odor. It requires transportation, storage environment dry, no dust, no smell, well-ventilated storage environment should be at room temperature that is available, preferably under 20% relative humidity conditions. Not allowed to close or volatile chemicals, particularly strong taste of oil or other items stored together.
