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.

A method for obtaining pure drinking water from dewatered biological products is described. The process is carried out in a hermetic dewatering chamber isolated from the ambient atmosphere and in parallel with a process during which dried products are placed on drying trays. All the process parameters, such as temperature, humidity, and appropriate pressure inside the chamber, are controlled. The vapor generated during the product dewatering process, released from the products, is continuously removed from the dewatering chamber through the upper opening, exits through the outflow channel, and enters through the condenser. The process of obtaining clean drinking water is carried out outside the chamber and is conducted in several stages: vapor passes through disinfectant grids, vapor flows to a condenser cooled with ice water, and the vapor condenses on densely arranged lamellas. The condensate is then pumped to a discharge tub.

In some examples, a convective gas bar can include a gas inlet to receive supply gas to a first portion of the convective gas bar, feed holes located in the first portion, a nozzle plate located in a second portion of the convective gas bar, where the nozzle plate includes nozzles, and the nozzles are adapted to receive and direct the supply gas from the feed holes through the nozzles.

A system for drying a battery plate grid is disclosed. The system includes a pair of heated rollers disposed adjacent to one another, and a conveyor belt arranged to transfer the battery plate grids toward the heated rollers, such that the battery plate grid passes between, and comes in contact with, each of the heated rollers. The system includes a convection oven arranged to circulate convection heat around the battery plate grid when the battery plate grid completes transfer through the heated rollers.
