The invention discloses a roller mill for ultra-fine crushing, which comprises a sieve-shaped grinding disc arranged on a support, a roller mill sieve hole is opened on the sieve-shaped grinding disc, and a horizontal roller shaft is arranged above the sieve-shaped grinding disc. The outer wall of the roller shaft is fixedly connected with a vertical shaft, and the vertical shaft is driven to rotate by a power device. A roller is installed on the horizontal roller shaft, and the roller is in close contact with the upper surface of the sieve-shaped grinding pan. The remarkable effect of adopting the present invention is that, through the cooperation of the sieve-shaped disc and the roller provided with the roller milling sieve holes, the food raw materials are extruded, rubbed and sheared synergistically, and the dry, wet or oily food The raw materials are rolled and crushed, and the crushing effect is good. It is especially suitable for ultrafine crushing of food. The finished product can pass through a sieve of 300-500 mesh or more. The effect is very significant, and the structure is simple and the cost is very low.

The invention provides an automatic sterilization cleaning toilet which comprises a toilet lid, a seat ring and a seat barrel, wherein a cleaning spray head is arranged at the inner side, facing the seat barrel, of the toilet lid; the cleaning spray head comprises a rotating cleaning spray head used for cleaning the seat ring and a seat barrel cleaning spray head used for cleaning the seat barrel;the cleaning spray head is connected with a sterilization cleaning gas-liquid supply device; the sterilization cleaning gas-liquid supply device is connected with a control system through an electromagnetic valve; an opening and closing motor is arranged on the seat barrel; a human body sensing device is connected onto the toilet lid; and the human body sensing device and the opening and closingmotor are connected with the control system. Through being controlled by the control system, the toilet lid is closed, the rotating cleaning spray head automatically rotates and sequentially sprays sterilization cleaning agents, water and hot air to automatically sterilize, clean and dry the toilet seat ring; and the seat barrel cleaning spray head sequentially sprays the sterilization cleaning agents and high-temperature water to clean the inner wall of the seat barrel. The automatic cleaning and sterilization on the toilet are realized; the sanitation problem of the toilet in a public area is solved; and the trust degree of the user on the toilet sterilization state is improved.

The present invention is powder surface coating process and apparatus. During coating powder, the powder is made to fall spirally in a vacuum environment and a homogeneous cladding is formed on the surface of the powder. The apparatus for coating powder includes one vacuum chamber, a vacuum film coating source, and a vacuumizing system. Inside the vacuum chamber, there are one turned conic rotaryhopper, one feeding chamber connected to the upper end of the hopper, and collecting chamber connected to its lower end. The vacuum film coating source mounted in the middle part inside the hopper has one speed adjustable motor for rotating the hopper. The present invention has great coating capacity and low running cost.
