Disclosed is a piston press of the type used in the field of the dehydration of products to be dehydrated such as sludge from a purification plant. More particularly, it relates to a piston press including a pressing chamber supplied with sludge and able to manage air streams that it generates, and to a method for using such a press. In a preferred mode of embodiment, the piston press includes a pipeline having a water removal branch and arranged so as to remove water extracted during a sludge-pressing operation, and an air circulation branch that can channel the volumes of air circulating in the press during the operation thereof, so as to direct the vitiated air, i.e. air that has been brought into contact with the sludge during the implementation of the press, towards a deodorization system.

A filtration assembly for separating solids from liquids contained in a sample, and a method for preparing such a sample are disclosed herein. According to one embodiment, the filtration assembly includes an inner element (100) with proximal and distal ends (102,103) and a sample (200) disposed therein. A reinforcing sleeve (300) is disposed around the inner element (100) to form a sample receiver (250) with proximal and distal ends (252,253). A filter (400) is disposed at the open proximal end of the sample receiver (252) and a filtrate receiver (500) is placed over the filter (400) and threadedly engaged with the sample receiver (250) to clamp the filter (400) therebetween. Then, the receivers (250,500) are inverted and a pressure is applied to the sample (200) to force a liquid component (200a) through the filter (400) into the filtrate receiver (500), while solids (200b) are retained in the sample receiver (250).

A press is used to extract juice from food matter contained within a cartridge. The cartridge is compressible by the press and juice can be expelled through a cartridge outlet extendible through the press region.

Apparatus for forming a cake of compressed plant material, comprising a bottom die having a cylindrical upper portion, an inverted conical lower portion and a post extending vertically upwardly from a small-diameter region of the lower portion, wherein plant material is introducible into a cavity of the bottom die surrounding the post; a top die designed and configured to conform to the cylindrical upper portion and the post and having an inverted conical lower portion with a narrower diameter than a corresponding portion in the bottom die; a power train operable to drive the top die into the bottom die so as to be in pressing relation with the plant material interposed between the top and bottom dies for a sufficient duration to produce a cake of compressed plant material.

Embodiments related to juicing methods and apparatuses for extracting juice from food matter using juicer cartridges are described. In one embodiment, a juicer cartridge may include one or more separate internal compartments. Food matter loaded into the juicer cartridge may be compressed by a corresponding juicer and expelled through an outlet that may be sealed until activation. Food matter may be pre-sized according to various physical characteristics, and the juicer cartridge may be injected with a gas to enhance shelf life and reduce nutrient loss. The juicer may also be provided with smart functionality to provide safety features, track usage, and enhance the operator experience. Several embodiments of packing systems for preparing juicer cartridges are also described.

A juicing machine comprises an electric motor; a variable frequency drive configured to control the speed of the electric motor; a juicing mechanism that has at least one extraction assembly that operates cyclically to extract juice; and at least one sensor that determines the position or positions of the extraction assembly during a cycle.

An apparatus for filling the basket of a portafilter of an espresso machine with a predetermined dose of coffee grounds and for pressing it within the portafilter comprises a frame having a front wall, a support device for supporting the portafilter, which projects out of said front wall, and upon which the portafilter is placed, a first emplacement, configured on said support, in which said portafilter is placed for filling a predetermined dose of coffee grounds in its basket, a conduit with its opening facing said first emplacement configured on the support, a dispenser device for dispensing coffee grounds and cause a predetermined dose of coffee grounds to reach the basket of the portafilter, through said conduit, a second emplacement, configured on said support, in which said portafilter is positioned with the basket filled with the predetermined dose of coffee grounds, upon displacement thereof from said first emplacement, a pressing device for pressing the coffee grounds, mechanical means for supporting said pressing device in cantilever fashion from said frame, in a vertically aligned position above said second emplacement as well as motor means for moving it toward and away from the dose of coffee grounds contained in the basket of the portafilter.

A pathologic staging compression device prepares a biological sample for pathologic staging by compressing the sample to remove liquid fat from the sample. In one embodiment, the apparatus preferably includes a compression tube, a removable drainage planum to hold the compression tube, a fat containment and drainage system, a gauge to monitor the extrusion force, use of hydraulic pressure to generation the extrusion force for sample compression, and ejection of the compressed sample after the compression tube has been removed from the drainage planum. In another embodiment, the apparatus includes an integrated riser assembly to stabilize and align the compression tube.
