Abstract
A heat press for extracting fluid, such as oil, from a biological plant. A lower heat platen is fixedly attached to a main frame and an upper heat platen is retractably positioned opposite to the lower heat platen. A pneumatic or hydraulic cylinder or a manual or electronic linear actuator provides pressure to an actuation means that is operatively connected to the upper heat platen for initiating movement. A control mechanism that consists of a single pressure regulator system or a dual pressure regulator system is used to control pressure of a pressing operation of the heat press. Alternatively, a digital regulator system can be used to control pressure, time, and temperature of a pressing operation of the heat press. At least one of the upper and lower heat platens has embedded heating elements and an isolated thermocouple. A user interface panel, having an LCD display, a user keyboard, or a touchscreen display is also mounted to the main enclosure.
