The present invention relates to a system (1) and method (100) for drying a residual product (12) from a foodstuff production process, the residual product containing between 20-50% dry substance. The method comprises the steps of producing a main foodstuff product (4) in the foodstuff production process (2); receiving the residual product continuously from the foodstuff production process; supplying the residual product to a mixer (30); supplying the mixed product (31) to a fluidized bed (40); supplying heated air (57) of between 60-150 degrees C. to the fluidized bed; drying the mixed product in the fluidized bed using the supplied heated air by shaking the mixed product; cooling the dried product; and extracting the dried product (42) from the fluidized bed, wherein a portion (62) of the dried product is supplied to the mixer to be mixed with received residual product (12).

The invention relates to the field of processing materials, and more particularly to a method for processing heat-sensitive materials in a vortex chamber, and can be used for drying, comminuting, heat treating and simultaneously separating into fractions such heat-sensitive materials as grass, straw, herbal raw material, vegetables and other materials, or mixtures of different plant materials, as well as for processing agricultural waste, in particular poultry droppings and horse or cow manure, into safe organic materials such as, for example, fertilizers. A vortex chamber contains a rotor for comminuting material and is designed to be volume-adjustable, wherein the lateral wall is configured in the shape of a right circular cylinder and the outer surface of the lateral wall and/or the lower wall of the vortex chamber are provided with additional openings for the removal of processed material. The invention is intended for obtaining several end products with different consumer properties (fineness, wetness, density, etc.) from a material, wherein said products can be obtained simultaneously.

A batch sample preparation apparatus (10) for preparing a geological sample for analysis is described and claimed. The apparatus (10) comprises a dryer (12) having a drying (chamber 52), a sample inlet (20) and at least one sample outlet (22), (24) communicating with the drying chamber (52), to a comminution device (14) in selective fluid communication via valves (26), (28) with the dryer (12) to selectively receive dried sample. The apparatus (10) has a source of fluid (74) introduced at the dryer (12) so that sample material may be transported from the dryer (12) to the comminution device (14) by fluid flow, which fluid flow also extracts the sample material from the comminution device (14) for collection and subsequent analysis.

Methods, apparatuses, and systems for a closed loop product drying process are disclosed. Heated dry air enters a drying chamber, extracts moisture from a product to be dried, and exits the drying chamber, cooler and wetter. A heat pump air handler dries and warms the air from the drying chamber exhaust, and returns it to the drying chamber, in a closed air loop. The heat pump air handler includes a dehumidifier means in the closed air loop flow path. The dehumidifier means removes entrained moisture from wet air exiting the drying chamber, reheats the air, and returns it to the drying chamber.

Drying and separation vibrating fluidized bed for processing wet coal by high-temperature hot air. Wet coal is fed into a vibrating separation chamber connected to a hot air supply duct. The wet coal is vibrated as it is dried and is layered as heat and mass transfer occur between the high-temperature air and the wet coal particles. Hot air enters the bottom of separation chamber through a distribution plate that includes asbestos fiber cloth sandwiched between clamping plates. The wet coal is fed through a feeding distribution device that separates the coal pieces as they enter the separation chamber. After the coal is dried and layered, the heavy and light material exits the separation chamber through two discharge impellers.

A method and an apparatus for performing charging port detection control are provided, where the method is applied to an electronic device, a communication port of the electronic device has a functionality of obtaining power from an external power source for the electronic device, and a power path switching unit of the electronic device is arranged to control electrical connection between a system within the electronic device and a battery of the electronic device. The method may include the steps of: performing charging port detection; and control operation(s) according to the charging port detection. For example, the method may include: controlling the power path switching unit to have different configuration according to the charging port detection in order to charge the battery with different charging profiles; and detecting the system voltage level during charging for switching from the constant current mode to the constant voltage mode.

Herein is disclosed a spin flash dryer further comprising a waste outlet arranged in a chamber bottom of the spin flash dryer for removal of a residual organic waste material from a spin flash dryer during spin flash operation and a method of operating a such spin flash dryer to remove residual organic waste material from said spin flash dryer during operation.

A gas-particle processing method comprising: introducing gas into a chamber through a gas inlet; flowing the gas through the chamber from the gas inlet to the gas outlet at a first controlled mass flowrate; introducing at least one particle stream into the chamber through one or more particle inlets of the chamber at a second controlled mass flowrate; flowing each particle stream through a respective processing region in the chamber; and controlling the first and/or second mass flowrates, such that the gas-particle mixture porosity in a substantial portion of each processing region is 0.900-0.995.

The present invention relates to the use of a mechanical apparatus to convey a workpiece through a fluidized bed dryer. In particular, the invention relates to a single or multiple stage vibrating fluidized drag conveyor having spaced apart conveyor paddles attached to a continuous chain or a similar device, and driven by a variable frequency motor drive. The invention is of particular applicability in the case of low-density workpieces where chaotic motion of air may disrupt or reverse the orderly flow of workpieces through the dryer.

Herein is disclosed a spin flash dryer further comprising a waste outlet arranged in a chamber bottom of the spin flash dryer for removal of a residual organic waste material from a spin flash dryer during spin flash operation and a method of operating a such spin flash dryer to remove residual organic waste material from said spin flash dryer during operation.
