Herb oil pressing devices and methods are provided. The devices include a pair of closable opposed jaws that can apply pressure to a herb placed between the jaws; a motor connected to the jaws for controlling the closing of the jaws, and, when closed, controlling the pressure produced between the jaws; a heater connected to the jaws for heating the jaws and herb; a housing in which the jaws, the motor, and the heater are housed; and a user interface connected to the jaws and the heater, the user interface for inputting a selection of temperature, pressure, and amount of time the temperature and pressure is applied to a herb positioned between the jaws to extract oil therefrom. Related computer-implemented methods of pressing a herb are also provided.

Provided is a press-forming apparatus including: a punch; a die having an inclined surface inclined toward a hollow part into which the punch is inserted and; a die plate holding the die; a blank holder having a holding surface facing the inclined surface of the die; a die load sensor detecting a load in a pressing direction, a load in a first direction perpendicular to the pressing direction, and a load in a second direction perpendicular to the first direction; a controller that calculates a normal force of the die based on the loads in the pressing direction, in the first direction, and in the second direction, the loads being detected by the die load sensor, and calculates the amount of correction of clearance between the die and the blank holder based on the normal force of the die; a first driver that moves the die in the pressing direction based on the amount of correction of clearance; and a second driver that drives the punch in the pressing direction.

The roller crusher further includes at least one load sensor configured to detect a material load in the deflection distributor and at least one positioning sensor configured to detect a parameter pertaining to a distance between a first point and a second point of the roller crusher. At least the first point is defined on the deflection distributor or on one of movable bearing housings of the roller crusher. The disclosure further relates to a method for monitoring the physical condition of the deflection distributor and to a refitting kit for a roller crusher.

A method for operating a forming press which includes a plurality of press components and a plurality of tool components. The forming press has at least one force sensor and at least one force actuator, each arranged in a press and/or tool component. A forming simulation is carried out, which takes into consideration an elastic behavior of the press and/or tool components. Target values of forces acting on at least one press and/or tool component are determined by the forming simulation. A forming process is carried out by the forming press. During the forming process, actual values of forces acting on the press and/or tool components are measured by the force sensor and the force actuator is actuated via a control loop such that the actual values correspond to the target values from the forming simulation.

The pressing of an article is achieved with a closed-loop feedback press. The closed-loop feedback press is effective to measure an amount of pressure applied and adjust the pressure to achieve a prescribed amount of compression on the article. Further, the press may leverage a closed-loop feedback system to maintain a consistent temperature of one or more platens. The press is able to adjust a pressure applied one or more times during a pressing operation to accelerate a temperature change in the pressed article while reducing the pressure applied as the temperature approaches a target temperature to limit unintentional deformation and bleeding of the pressed material of the article.

Described is a rosin press system for extracting rosin (oil) from plant material. The rosin press system includes a male plate with a male protrusion and a female plate formed to matingly receive the male protrusion. The plates can be heated such that when plant material is pressed between the plates, rosin is pressed from the plant material and allowed to drain from a drain hole positioned at the middle of the female plate.
