In forward-feed operation as shown in Fig.2, the fresh feed is added to the first effect and flows to the next in the same direction as the vapor flow. This method of operation is used when the feed is hot or when the final concentrated product might be damaged at high temperatures. The boiling temperatures decrease from effect to effect.

There are two types of bead mill that are effective in grinding to the nano range, but we favor the high-energy pin mill over the disc mill for a number of reasons. First, because a 20-liter disc mill has 25 or 30 hp, as does a 10-liter pin mill, which makes the lower-capacity pin mill capable of running at higher tip speeds. Higher tip speeds

The production of fish meal and oil - 3. The process
A number of methods have been devised where the raw materials are dried without preliminary cooking. These are particularly suitable for lean fish (less than 3% fat) and offal, but may, in some circumstances, also be adapted to treat fatty fish species. By the Schlotterhose method, lean fish is dried in two stages, using indirect steam dryers.

Different methods of pulping with bagasse raw material
Mechanical method and thermal grinding mechanical method. The bagasse is coarsely ground and finely ground at a concentration of 6-7% with a double disc mill. After coarse grinding, the pulp is thickened by a screw press to about 30% pulp concentration. The refined pulp is purified by a screening machine and then bleached.
DE-11: Lesson 43. SIZE REDUCTION
f) Pin (Pin-Disc) Mill In one type of pin mill a stationary disc and rotating disc are located facing each other, separated by a small clearance. Both discs have concentric rows of pins, pegs or teeth. The rows of one disc fit alternately into the rows of the other disc. The pins may be of different shapes; round, square or in the form of blades.
Feed Mills - Central Silo Systems
The disc mills from SKIOLD are suitable for grinding of many different types of raw materials, including pellets with a diameter of up to 12 mm. One of the advantages of the disc mill is that it is possible to vary the grinding degree during operation, and thereby optimize the feed structure for different animal groups.
Disc Filter - an overview | ScienceDirect Topics
Trevor Sparks, George Chase, in Filters and Filtration Handbook (Sixth Edition), 2016. 2.8.2 Stacked disc filters. Stacked disc filters are similar to the edge filter in appearance, in that they have an array of disc-shaped components held on a central core. The stacked disc filters differ however in that the discs are actually hollow, with filter media over the faces of the disc.
