Abstract
A hand-operated screw press for users to press cannabis flower or isolated trichome heads without an air compressor, hydraulic unit or solvents used in the process. A digital load cell is provided, as is a full color LCD touch screen display for showing and recording force in real time. A mechanism for detecting the end point of a process is also provided. A recipe representative of heat plate temperature, time of operation, pressure ramping, capacity of the screw press, type of raw material, or mass of raw material can be created and stored for use on any suitable rosin press machine.
Claims14
A hand-operated, solventless screw press, comprising:
- a) two oppositely disposed heat plates for generating force to raw material in order to extract oil therefrom, the heat plates are an upper heat plate and a lower heat plate;
- b) a rotatable handle operatively connected to at least one of the two heat plates for adjusting a distance therebetween;
- c) a force measuring digital load cell operatively in contact with at least one of the heat plates;
- d) a display operatively connected to the load cell for displaying pressure being applied by the heat plates in real time;
- e) a structural frame including guide rods surrounding and holding the upper heat plate and the lower heat plate in place, the guide rods resisting rotary forces from the handle and translating force from the handle into linear movement of at least one of the heat plates;
- f) a lead screw disposed between the guide rods and connecting the handle and upper heat plate, wherein the handle is rotatably mounted to a shaft of the lead screw such that rotational movement of the handle is translated into a vertical force on the upper heat plate;
- and
- g) at least one compression spring disposed below the lower heat plate and configured to apply an upward force to lift the lower heat plate off the load cell.
