Described herein are devices and methods for drying biomass using smoke. A device may include a housing configured to receive the biomass; at least one sensor in the housing and configured to measure a property of the biomass; a heat source thermally coupled to the housing and configured to apply heat to the housing and thus the biomass therein; and a smoke producing chamber fluidly coupled to the housing and configured to receive a burnable material therein.

Methods and apparatuses for drying, especially cannabis, are provided. One of the provided methods includes: heating the cannabis in a cavity of a variable frequency microwave oven using at least two different frequencies; measuring temperature of at least 1 cm square of the cannabis at different times during the heating; and controlling the heating based on the temperature measured so that the cannabis is kept for at least 20 minutes at temperatures above 30° C. and below 100° C.

The continuous process of the present invention is intended to obtain dry biomass from two treatment steps by drying organic waste. The waste previously sieved and crushed waste are dumped into a first dryer, inside of which temperatures are between 280° C. and 300° C. at the inlet thereof and between 90° C. and 100° C. at the outlet, then passing to a conveyor belt where at room temperature a partial cool-down occurs and the waste is dumped into a second dryer inside of which the temperatures are between 180° C. and 200° C. at the inlet and between 75° C. and 85° C. at the exit, completing the process, during which the interior of the dryers is maintained in negative pressure through exhaust flow and the oxygen content is kept between 5 and 7%.

Devices, systems, and methods for drying a bulk waste product, such as animal waste, having a moisture content of 95% or more water can include a trough configured to receive the bulk waste product and to dispense it in a form suitable for convective drying, one or more conveyors having an air-permeable conveyor belt, each conveyor receiving the waste product from the trough and transporting the waste product along a transport path; and one or more air moving devices (AMDs) that pass air through the air-permeable conveyor belt and across the waste product as it is transported along the transport path to transform the bulk waste product into a dried waste product having a moisture content of about 5% to about 20%, inclusive.

Systems and methods are provided for drying plant material using molecular sieves.

In a method for physical and thermochemical treatment of biomass, the biomass moisture content is reduced in a dryer and ammonia (NH.sub.3) is also released from the biomass during drying. The dried biomass is then either pyrolyzed in a pyrolysis reactor and the pyrolysis gas is forwarded to and combusted in a combustion device to form flue gas, or is combusted in a combustion facility unit to form flue gas. In either case the flue gas is fed to a mixer. Oxygen (O.sub.2) is metered to the flue gas in the mixer and is fed directly to the dryer as drying gas. As the drying gas passes through the dryer, the sulfur dioxide (SO.sub.2) contained in the drying gas and/or the sulfur trioxide (SO.sub.3) chemically reacts with the ammonia (NH.sub.3) to form ammonium sulfite ((NH.sub.4).sub.2SO.sub.3) and/or ammonium sulfate ((NH.sub.4).sub.2SO.sub.4). Also a treatment facility physically and thermochemically treats the biomass.

A system that facilitates the controlled drying of biomass is provided. The system and method provides automated control over the rate of drying and the moisture content of the resulting product. The system and method also includes auto-loading and unloading, thereby providing a fully automated process. The system and method can be adapted to match the scale of the production and therefore has applicability for large operations as well as micro operations. In addition, since the drying rate and moisture content of the material being dried is monitored and controlled, the system and method can be used to dry products for a wide range of different applications (e.g., drying hemp for medical use as well as for industrial use).

A hemp biomass drying assembly that is disposed within a structure and having a central lift assembly, a rotatable tine assembly, an auger assembly, and a track drive assembly that are all connected to a control system to activate and operate all assemblies. The drying assembly has multiple modes of operation that include a spreading mode, a leveling mode, and stirring mode, and an unloading mode.

A system for drying plant material comprising an enclosed space having a ceiling, a wall, an enclosed space first portion, and an enclosed space second portion. An air supply provides tempered air into the enclosed space proximate to enclosed space first portion. The system includes at least one air mover, positioned proximate to the ceiling at the enclosed space first portion, having an air mover inlet and an air mover outlet. The system further includes a duct horizontally arranged and having an elongated body, a duct open first end portion, and a duct closed second end portion. A plurality of openings is spaced apart in a predefined pattern on the elongated body. A dehumidifier is positioned proximate to the enclosed space first portion.

Embodiments disclosed herein provide an organic matter processing apparatus and method for the use thereof to convert organic matter into a ground and desiccated product. The organic matter processing apparatus includes a lid assembly that is positioned at the top or head of the processing apparatus and an air treatment system. The lid assembly is operative to open to allow a user to deposit organic matter into the processing apparatus or to remove a removable bucket contained therein. The lid assembly is operative to close and provide an odor containing seal that prevents or substantially mitigates escape of odor. The air treatment system uniformly distributes untreated air through an air treatment chamber to convert the untreated air to treated air, which is exhausted out of the processing apparatus.
