A food material powder supply device 1 of the disclosure includes a supply tank 50 that temporarily stores food material powder in a tank 50A and supplies the food material powder to a processing container 2A of a food processing machine 2, a vacuum device 70 that reduces the pressure inside the supply tank 50 with vacuum pumps 71A and 71B, and a control device 3 that operates the vacuum device 70 to reduce the internal pressure of the supply tank 50 to be equal to or lower than a predetermined atmospheric pressure at which moisture of the food material powder is evaporated and cools the food material powder in the supply tank 50. A stirring member 54 which is driven to rotate during the cooling of the food material powder is arranged inside the tank 50A.

An exemplary method for preserving fresh herbs includes obtaining fresh trimmings from a plant, grinding and/or chopping the fresh trimmings to form processed trimmings, packaging the processed trimmings in a container, and freezing the processed trimmings in the container. Freezing the processed trimmings may include subjecting the processed trimmings to a dry ice atmosphere.

A frozen condiment selected from the group consisting of sauces, pastes, pts, creams and pizza toppings, having hygienic and organoleptic features comparable with those of a corresponding fresh condiment, which is in the form of granules having a porous surface, having an average weight of 6.0 g or less and essentially homogeneous in size having a diameter comprised between 1 mm and 20 mm, and apt to determine a rapid and uniform thawing of the deep-frozen condiment.

Disclosed is an automatic immersion ice-coating machine, including a frame, an ice-coating working pool, a feed port, a conveying device, a control system and a driving system. A first side of the ice-coating working pool communicates with a buffer tank. A bottom of the ice-coating working pool is stepped or inclined, and a drain valve is provided at a bottom of the ice-coating working pool. The conveying device includes a first conveyor belt and a second conveyor belt. The first conveyor belt is located under the feed port, and a lower portion of the first conveyor belt is lower than the liquid level, and the second conveyor belt communicates with the discharge port. The first and second conveyor belts are made of stainless steel mesh belts, and surfaces of the stainless steel mesh belts are provided with separators in a spaced manner.

An elliptical and funnel-shaped jet nozzle structure includes a plurality of elliptical tapered diversion channels, a plurality of elliptical jet nozzles and a conveyer belt. A wall thickness of each of the elliptical tapered diversion channels is 1-5 mm. A wall thickness of each of the elliptical jet nozzles is 1-5 mm. A thickness of the conveyer belt is 1-5 mm. The elliptical tapered diversion channel is a hollow elliptical truncated cone and it includes an upper opening and a lower opening. The upper opening of the elliptical tapered diversion channel is connected to an elliptical opening, and the lower opening of the elliptical tapered diversion channel is connected to an inlet of the elliptical jet nozzle. The elliptical jet nozzle is a hollow elliptical cylinder.

A conveyor belt (36) is arranged in at least one spiral conveyor unit (32) or (34) is arranged in tiers forming at ascending spiral stack (38) and/or a descending spiral stack (40). A ceiling or top sheet (58) is positioned over the spiral stack. A circulation fan (60, 62) draws spent thermal processing medium laterally from the tiers of the spiral stack, up the exterior of the stack and across the top of the stack above the ceiling or top sheet and through a heat exchanger (64) located above the ceiling. The treated thermal processing medium is then routed across the remainder of the diameter of the spiral stack and then down the side of the spiral stack diametrically opposite to the circulating fan thereby to enter the spiral stack in a lateral direction diametrically toward the circulating fan. At least one opening (70, 100, 200) is formed in the ceiling between the heat exchanger and the diametrically distal end of the spiral stack from the circulating fan thereby to provide an alternative flow path for a portion of the thermal processing medium to enter the spiral stack from above, thereby resulting in more uniform treatment of the work product being carried by the conveyor of the spiral stack.

A cooler including a compartment, a conduit including a first end portion configured to be in communication with the compartment and a second end portion, food product at a first product temperature entering the first end portion, a fluid discharge positioned substantially within the conduit between the first end portion and the second end portion, and a pressurized fluid source in communication with and for supplying fluid through the fluid discharge, the fluid being at a first fluid temperature less than the first product temperature, the pressurized fluid source being operable to propel the fluid through the fluid discharge to move the food product from the first end portion of the conduit toward the second end portion and to cool the food product to a temperature below the first product temperature.

A horizontal axis rotary separation apparatus is deployed in a process for separating resinous trichomes rich in flavoring, aromatic and/or medicinal components produced in plant trichome glands from unwanted plant matter. The process physically separates resin rich beads at the trichome gland head from extraneous plant matter by one or move separation sieves. The sieves are provided in or as a casing over a rigid frame member. The sieves are mesh fabric bags or screen that are easily opened and replenished in a batch operating mode, and are removable from the frame for cleaning and maintenance. Other aspects of the invention include processes that improve process efficiency and speed, and yield products of superior quality.

A frying unit, comprising an oil pan (1) which is essentially open on top, a transport unit (2), using which a basket (3) is movable from a filling position into the interior of the oil pan (1) and using which the basket (3) is movable from the interior of the oil pan (1) into an emptying position, wherein the oil pan (1) is designed in such a way that it can accommodate multiple baskets (3) simultaneously, and the transport unit (2) is designed in such a way that the baskets (3) are movable independently of one another.
