Described herein are systems and methods for determining dryness of produce using image data. A method can include receiving, by a computing system and from an imaging device, image data of a batch of produce, performing, by the computing system, object detection to identify each produce in a frame of the image data, extracting, by the computing system, temperature values in pixels of the identified produce in the frame, and determining, by the computing system, distribution characteristics of the extracted temperature values. The method can also include predicting, by the computing system, a dryness metric for the batch of produce based on applying a trained model to the determined distribution characteristics. The model can be trained using temperature distributions of other produce, the temperature distributions being annotated based on previous mappings of skewness of the temperature distributions to dryness.

An apparatus and a method is provided for continuously drying bulk goods, in particular wood fibers and/or wood chips, in a dryer, wherein the drying vapors are led to a dryer circuit, in which the drying vapors are indirectly heated via a heat-exchanger and are conducted to the dryer again.

An apparatus for drying materials is disclosed. The apparatus has a chamber which is heated to a temperature sufficient to vaporize the water in the material into steam. The dryer is configured to utilize the steam produced from the material to condition the material. The dryer has two exhaust stacks positioned at opposing ends of the dryer. The removal of exhaust steam at the two opposing ends of the dryer facilitates the migration of moisture within the chamber along a length of the dryer between the two ends. The exhaust stacks can be controlled and adjusted based on feedback from a plurality of pressure differential transmitters installed within the chamber. Methods for drying materials are also disclosed.

A device for controlling the temperature of, and in particular for drying, objects, in particular vehicle bodies, having a housing which integrates a temperature-control chamber that includes at least one air outlet and at least one air inlet. The temperature-control chamber is assigned at least one heating unit in which it is possible to generate a hot primary gas flow and to which it is possible to supply, from the air outlet, air that is to be heated. The heating unit includes a heat exchanger device into which the hot primary gas can be guided and in which it is possible to heat air from the temperature-control chamber using hot primary gas, which air can be supplied, as heated recirculation air, in a circuit via the at least one air inlet back to the temperature-control chamber. The heating unit includes at least a first and a second flow outlet via which heated recirculation air leaves the heating unit.

A mobile steel grit dryer used to dry steel grit may be configured with a number of different functions and features to assist a contractor in performing steel or other structure maintenance when using steel grit in resurfacing the structure. The steel grit dryer may be configured with a heat process vacuum bypass so that an off-board vacuum, such as a vacuum on a grit recycling system, may be utilized as opposed to having an onboard vacuum. The dryer may include multiple modes so that an operator may use different modes for different environmental conditions. An exoframe may provide for better durability when being transported to different jobsites. A variety of automation and safety features may also be provided to simplify and improve safety for operators.

A material drying system provides for consistent and efficient drying of organic materials, such as cannabis. In certain embodiments, a partial vacuum drying system is used to dry the materials and includes a container, a heating system, a depressurization system, and a control system. Air in the container is heated to within a range of temperatures and a low vacuum is applied to assist with evaporation. In addition, the volume flow rate of air pulled out of the container is monitored and maintained at a predetermined rate, which pulls moisture away from the materials so as to prevent degradation of the materials during the drying process while also reducing drying time. A relatively high air volume flow rate is maintained at low pressure by adjusting the area of an opening in the chamber.
