Aspects involve an aggregate plow system that may be used in a system for cooling aggregate, such as may be found in a batch plant involved in producing concrete. The plow system generally contacts aggregate as it is conveyed by a conveyor belt to create a furrow within the aggregate prior to dispensing of liquid nitrogen or other coolant onto the aggregate. Additionally, the plow assembly may mix the ingredients of the aggregate on the belt by disputing the aggregate piled on the conveyor belt. The formation of the furrow, in place of a mound of aggregate on the belt, aids in retaining liquid nitrogen in the furrow such that it may better penetrate into the aggregate and thereby improving cooling. In either and both ways, the plow assembly improves dispersion of the coolant on and into the aggregate as it is conveyed by the conveyor belt.

Mixing systems that include a mixer housing and one or more disk assemblies for mixing and processing materials is disclosed. The disks rotate to mix an additive into the material and to carry agglomerated solids toward a discharge of the mixing system. The disks may have a plurality of fingers or lobes which extend from a central portion of the disks.

Preloading a plurality of feed types of a feed mix for livestock in a mixing plant. Feed types are conveyed towards a mixer. Bunkers selectively discharge one of the feed types on a loading conveyor. A controller controls a preloading weight of the feed types to be discharged onto the loading conveyor. Feed types are individually discharge onto dump spots of the loading conveyor at the bunkers and terminate when a predetermined total weight is reached or interrupt when a maximum preloading capacity is reached or feed reaches the end of the loading conveyor. Feed types may be individually discharged from the bunkers onto the dump spots and the main component loaded into the mixer by a loading vehicle, such that the weight of the main portion and the weight of the supplemental portion add up to a programmed total weight of the main component.

The present disclosure relates to a continuous fermentation device that can ferment objects continuously fed thereinto while conveying the objects. The present disclosure provides a continuous fermentation device comprising a plurality of fermentation modules, each including: a conveyor belt, which transports objects that are continuously fed thereinto to be fermented from one side to the opposite side thereof; agitators, which is located on the conveyor belt; and an air diffuser, which is located on one side of the conveyor belt, in which the continuously fed objects to be fermented are fermented while being passed through the fermentation modules. According to the present disclosure, feeding of raw materials to be fermented, fermenting the raw materials, and discharging of the fermented materials are continuously performed so that it is possible to significantly reduce the processing time, thereby reducing the operation time of the production process. Accordingly, it is possible to achieve an increase in competitiveness, such as improved productivity, reduction of investment cost, etc., in the development of a method of mass production through solid-state fermentation, thereby innovatively reducing the production cost of the product.

A mobile concrete mixing unit has an aggregate bin divided into two compartments by a water tank provided within the aggregate bin. A hydraulic reservoir is provided within the water tank in order to cool the hydraulic fluid within the hydraulic reservoir and warm the water within the water tank. The water tank also helps to keep the aggregate warm and flowable when used in low temperatures. A lower portion of the water tank includes sides that slope inwardly so that aggregate within the bin can drop freely onto a conveyor belt without bridging between the water tank and the sidewalls of the aggregate bin.

A nozzle for the supply of biological material, in particular tissue cells, having a mixing chamber (11) which is delimited by a proximal end surface (21) and a distal end surface (22) spaced apart from the proximal end surface (21), at least one nozzle opening (23) which is formed in the distal end surface (22), and at least two supply ducts (30, 40, 50) which discharge into the mixing chamber (11). A first supply duct (30) is arranged in the proximal end surface (21) and discharges into the mixing chamber (11) coaxially to the nozzle opening (23) and a second supply duct (40) has an inlet opening (42) which discharges into the mixing chamber (11) laterally, in particular tangentially at the distal end surface (22).

Means for dispensing a powdery coloring substance onto the surface of a mix comprising stone, stone-like, glass or ceramic material. The means comprise at least one dispensing device for containing and dispensing a powdery coloring substance and at least one spreading device. The spreading device comprises at least one moving perforated plate which receives a metered amount of said coloring substance from the dispensing device and distributes it over the surface of the mix.

Mixing systems that include a mixer housing and a plurality of roller assemblies for mixing and processing materials is disclosed. Each roller assembly includes a roller that extends between sidewalls in the mixer housing and rotates to mix an additive into the material and to carry agglomerated solids toward a discharge of the mixing system. Each of the rollers may have a protrusion geometry formed in the outer contact surface, where each protrusion geometry is complementary to an adjacent roller.
