Systems and methods of aseptic processing of product can include a hopper for introduction of the product into the system and one or more components through which the product flows as it is processed through the system, an enclosure surrounding one more of the components, a gassing assembly comprising a plurality of gassing elements for maintaining a substantially constant flow of inert gas over the product as it travels through the components of the system, and filtered gas recirculation system that recirculates filtered air or gas through the enclosure. Such systems can be particularly advantageous for use in the cannabis industry.

An indoor air pollution-free cleanroom system which achieves artificial intelligence green and health building standards is disclosed. Based on an indoor air pollution detection and purification system combined with an efficient building design structure, a renewable energy system, a water resources management system, a circular economy and resource recycling, the requirements of high comfort and low energy consumption of the green building standards (LEED standards) and the healthy building standards (WELL standards) are achieved, the new artificial intelligence green and healthy building standards is achieved, and the advantages of controlling indoor air pollution, water pollution, noise pollution and carbon emission to be zero, extremely saving energy, improving the health and comfort of the living environment are achieved.

A fan filter unit and a control method thereof are provided. The fan filter unit includes a fan and a control module. The control module includes a logic judgment circuit, a fan power supply and a control circuit. The logic judgment circuit is connected to an apparatus power supply of a semiconductor apparatus. The logic judgment circuit is used to judge whether the apparatus power supply is shut down. The control circuit is connected to the fan power supply and the logic judgment circuit. If the apparatus power supply is shut down, the control circuit switches a fan power supply path from the apparatus power supply to the fan power supply.
