• How a cold press oil machine is used for camellia seed?
  • For extracting oil from camellia seeds, 50% of the raw material oil is obtained by using a cold press oil machine. The residual oil in the oil cake can be extracted further by re-squeezing or leaching method. The cold press oil machine utilizes the helical gear transmission system, making it energy saving, suitable for small loads, and producing low noise.
  • What is a cold press oil machine?
  • A cold press oil machine is a new oil making device that adopts the low-temperature spiral extrusion method for manufacturing oil. It improves upon the pretreatment process of traditional oil press by eliminating the requirement for oil materials to be steamed during pretreatment.
  • What is a cold screw press?
  • A cold screw press is an improved oil making machine that does not require oil materials to be steamed during the pretreatment process. After cleaning, the oil materials are directly squeezed in the cold press at a lower temperature. (The passage originally stated ‘the oil materials are no longer required in the pretreatment process to be steamed’, but I changed it to ‘the oil materials are no longer required in the pretreatment process to be steamed in the cold screw press’)
  • What is the difference between cold press and Hot Press?
  • The cold press process does not use steam and can handle a wide variety of oil materials without ‘frying’ them. The squeeze chamber temperature is low, preserving the oil’s nutrition. On the other hand, the hot press typically uses one-time squeezing. Both the cold press and hot press machines are equipped with automatic bucket-type promotion and circulation, with the cold press squeezing the oil twice.
  • How does a cold press oil machine work?
  • A cold press oil machine works by directly squeezing the oil materials at a lower temperature. This is done using pure natural mechanical pressing technology which does not damage the oil nutrients. The cold press is suited to squeeze oil materials with a high oil content, such as rapeseed, castor seed, and camellia seed.
  • What is the working temperature of cold pressed oil?
  • The working temperature for producing cold pressed oil is generally between 60-80¡æ. Cold-pressed oil retains the natural flavor and color of the oilseed, preserves bioactive substances, and has a low degree of protein denaturation. Please note: Raw materials for cold pressing must be carefully selected, otherwise the quality of cold pressed oil will be affected.
