The invention discloses a method for bacteria-reducing cleaning of fruits and vegetables in cooperation of ultrasonic waves and slightly acidic hypochlorous acid water. First inject a certain concentration of slightly acidic hypochlorous acid water into the ultrasonic cleaner, adjust the power and temperature of the ultrasonic cleaner to appropriate parameters, and then set the cleaning time to start working. The present invention can quickly sterilize the surface of fruits and vegetables under the condition of effectively removing dirt on the surface of fruits and vegetables. The co-treatment of acidic hypochlorous acid water will not affect the deformation and quality of fruits and vegetables. Slightly acidic electrolyzed water is broad-spectrum and efficient in sterilization, especially when it interacts with organic matter, it will be reduced to water. Compared with other current fungicides, it is safe and has no residue, and is friendly to the human body and the environment. The invention is suitable for sterilization and preservation of fruit and vegetable products, removal of pesticide residues, and can also be applied in the field of cleaning meat products.

A system (10) for recycling asphalt shingle scrap. There is a cold process, hot process, and a separation process. In the hot process, all of the components are ground except for the course surface granules. In the cold process, a type of grind is formed that is the same as the hot process except it is a dry powder. A horizontal mixer (20) can be used either hot or cold. The hot process and cold process can be run in combination with one another or independently. The component separation process uses a screen or the like (34) to separate the cold process material into surface granules, filled asphalt coating, and saturated felt component, while a magnet (38) may be used to help separate nails and other metal objects from the mixture.
