Factors of affecting oil output rate in cooking oil press machine

Cooking oil press machine

Following factors may affect oil output rate in cooking oil pressing machine line:

1,water contact: This is the critical factor,as a matter of fact, water content directly affects oil output rate

However,user usually has not proper inspection equipment.Hence,water content of some main raw material may be detected as follows:

1.1 Bean: If teeth beathing could crack it,forming flat pieces accompanied with light sound, the water content is suitable.Flat piece without cracking means too wet. Heating or sunshine may be drive water off.However,cracking accompanied with loud indicates too dry.Adequate water needs to be added.

1.2 Cotton seeds. Shell and kernel may be separated by teeth beating.Shell breaking may be accompanied by sound,which means water content is suitable.Shell being flatting incicates too wet,shell being splited into powder means too dry.

1.3 Rape seeds: They can be pressed either at hot or at cold state.Cold pressing : extruding by finger, if they splitted into two pieces, accompained by sound and oil , this implicates water content is adequate.Otherwiae,extruding makes, power indicates too dry? makes flat slice, too wet. Hot pressing(after heating); To scratch seeds by two slices of wood, if shell and kernel could be splitted, water content is adequate. If kernel becomes power, it is too dry;in the case that shell and can be splitted, it is too wet.

2. Cake thickness reflects the pressure inside the chamber.Thicker cake indicates lower pressure inside the chamber; thinner cake-higher pressure inside.If raw material has less oil content,chamber pressure shoild be higher, cake will be thinner, round plates need to be tightened; in the case of high oil content material, pressure in the chamber should be lower,then circular plates need to be looseded resulting in thicker cake. Recommended thickness of cakes will be.

 Bean : 1-1.5mm for the first time: 0.5-1 mmfor the second time.

 Cotton seeds: only one pressing, 1-2 mm.

 Ground nut kernel: Normally cold pressing for 2-3 times,1-2 mm

 Important note: cake thickness should be as a ccording to different factors to achieve higher oil output rate. Hence, above figures will only be for reference.
