A 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. A liquid freezing agent is introduced into a container of the plant matter to fragment the undesirable matter while the desired portion rich in trichome remain intact.

A method for removing moisture from an atmosphere within a freezer using a cryogen for freezing operations includes providing a freezing temperature with the cryogen at the atmosphere, reducing a temperature of the atmosphere with the cryogen for removing moisture in the form of droplets from the atmosphere, collecting the droplets on internal surfaces of the freezer, permitting the droplets to dwell for an amount of time in the atmosphere sufficient to freeze the droplets to become frozen droplets, and removing the frozen droplets from the freezer.

A method and apparatus for freezing a liquid droplet includes dispensing, by a liquid dispenser, a droplet of liquid into a fluid chamber containing a freezing fluid. The droplet of liquid is allowed to dwell in the freezing fluid for at least a predetermined dwell time so that the droplet of liquid freezes to a frozen droplet. The method and apparatus further includes injecting, by a gas injector, a stream of gas transversely to a surface of the freezing fluid at about where the frozen droplet is located along the surface of the freezing fluid contained in the fluid chamber so that the frozen droplet sinks in the freezing fluid.

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.

The efficiency of a device for cooling or heating objects on a belt that moves through a path of a helix, in which gaseous cooling or heating medium is circulated within the device, is improved by positioning fans that circulate the cooling or heating medium so that the fans are distanced from the top of the helix.

An apparatus, system, device, and the like, for a liquid nitrogen dispensing head that may be used in a system for cooling aggregate, such as may be found in a batch plant involved in producing concrete. The dispensing head is positioned over a conveyor belt that conveys aggregate to a mixing apparatus to produce concrete. The head dispenses liquid nitrogen onto the aggregate to cool the aggregate and may include interior chambers separated by one or more baffles. The chambers may reduce the pressure of the liquid nitrogen onto the aggregate in relation to the flow pressure of the liquid nitrogen entering the dispensing head. In another example, an assembly may include sidewalls that extend to the aggregate on either side of the head to form a cooling tunnel through which the aggregate is conveyed and is exposed to the liquid nitrogen being dispensed from the head.
