An apparatus including an air blower; a rotary airlock; a receptacle having an inner chamber supplied with a plurality of colorant particles; a water supply; and a mixing chamber. The air blower blows air into a bottom section of the rotary airlock, and the rotary airlock receives colorant particles from an output of the receptacle. A rotor shaft of the rotary airlock rotates to cause colorant particles to be transported to the bottom section of the rotary airlock. Air blown into the bottom section of the rotary airlock mixes with colorant particles transported into the bottom section of the rotary airlock to form an air and colorant particles mixture, which is blown out of a first output of the rotary airlock and combined with water to form a water, air, and colorant particles mixture, which is mixed with material in a mixing chamber. The material may be natural mulch.

A method and a system for coating products are provided. The method includes the steps of applying a coating liquid to a product and removing excess coating liquid from the product. It is desirable to provide a method and system for efficiently and reliably coating delicate or easily deformable products, such as products molded from a pulp fiber slurry. The method includes fixing the product to a receiving portion of a product carrier that is configured in the same shape as the product, such that an exterior surface of the product abuts the interior concave surface of the receiving portion of the device. A coating liquid is applied to the product in the product carrier. The product carrier is affixed to a centrifuging device and the coating liquid is dispersed over the surface of the product using centripetal force.

The present disclosure relates to a tobacco flavoring machine, comprising: a drum (1) capable of rotating about an axis thereof as a rotation center; a nozzle (6) disposed in the drum (1) to spray a liquid flavor to tobacco shreds in the drum (1); and a shoveling plate (5) arranged on an inner wall (11) of the drum (1) and extending from an inlet end of the drum (1) towards the interior of the drum (1), the shoveling plate (5) being disposed obliquely with respect to a generatrix (9) of the drum (1). The present disclosure improves the problem of the related art that tobacco shreds cannot flow smoothly from an inlet end toward an outlet end because a shoveling plate (5) is parallel to an axis of a drum (1).

An installation for treating mass-produced parts includes: a supporting structure with a supporting element, a basket carrier for at least two centrifuge baskets, a main drive device attached to the supporting structure and having a main drive and a longitudinal shaft, the longitudinal shaft being mounted rotatably about a main axis relative to the supporting element and being drivable rotatably about the main axis by the main drive, wherein the basket carrier is held suspended at the longitudinal shaft and is connected to the longitudinal shaft in a rotationally fixed manner, and a secondary drive device having at least one motor and, for each centrifuge basket, a drivetrain for rotating the centrifuge basket about a basket axis radially spaced from the main axis, wherein the at least one motor of the secondary drive device is arranged on the basket carrier.

A vaccine spray equipment includes a frame, a conveying device, a spray device and two liquid supply devices. The conveying device is disposed on the frame, and is configured to support and convey a chick frame. The spray device is provided on the frame and includes two rows of spray heads provided along the conveying direction perpendicular to the conveying device, the two rows of spray heads are provided side by side above the conveying device. The two liquid supply devices are provided on the frame. The two liquid supply devices are respectively connected to the two rows of spray heads in a one-to-one correspondence, and each of the liquid supply devices is configured to provide the spray device with vaccine suspension liquid.
