Raw material preparation
The main ingredients of compressed biscuits include wheat flour,sugar,grease,food additives(such as leavening agents,emulsifiers,etc.),and water or other liquid ingredients.
These ingredients need to be precisely weighed according to a specific formula ratio and blended evenly.
Raw material molding
Feed the mixed material into the feed system of the single sheet press.
The compression roller of the single sheet press evenly squeezes the raw material into the desired shape,such as round,square,etc.,by setting the pressure and speed.
In this process,the thickness and hardness of the biscuit can be controlled by adjusting the pressure and speed of the compression roller.
Cutting and forming
Once the ingredients are compressed into shape,the single sheet is cut precisely through the cutter to form the size and shape of the individual cookie.
The cut biscuits can go straight into the oven or other subsequent processing equipment.
Baking and cooling
The cut cookies need to be sent to the oven for baking to remove the moisture and cure them.
After baking,the cookies need to be cooled on a cooling device for subsequent packaging and storage.
Single press tablet machine-Catalyst making
Select the right catalyst material powder to ensure that it is dry,clean and uniform.
According to the formula of catalyst,all kinds of raw material powder are mixed evenly according to a certain proportion.
Feed the mixed catalyst raw material powder into the feed port of the single sheet press.
The shape,size and hardness of catalyst tablets can be controlled by adjusting the pressure,speed and time of the tablet press.
The single sheet press uses high pressure to press the raw material powder into a solid shape catalyst tablet.
After the pressing is complete,remove the catalyst tablet from the tablet press.
