Bread, being the most massive piece of food cargo with the shortest shelf life, requires strict sanitary regimes, poorly withstands mechanical stresses, especially in the first hours after baking. With this in mind, an important role should be assigned to transport and storage operations. However, in comparison with the level of mechanization of the main production, the mechanization of transport and storage operations with finished products is significantly behind, barely reaching 10 ... 15%. [...]

 From the sorting table, bread products are sent to tray or trayless containers. For tray containers, three- or four-sided trays are used with a trellised (for rye, rye-wheat, shaped and hearth varieties) or solid (for loaves, rolls, muffins) bottom. Currently, plastic trays are widely used, which are quite light and well amenable to sanitary treatment. Fig. 3.51. Container For transportation [...]

 From the sorting table, bread products are sent to tray or bezlotkovye containers. For tray containers, three- or four-flanged trays with trellised (for rye, rye-wheat, tin and bottom varieties) or solid (for long loafs, buns, baking) bottom are used. Currently widely used plastic trays, which are quite light and are well sanitized.

Presses differ in the design of the dispensers, the number of chambers in the dough mixing machine and their location, the number of pressing screws, the design of the pressing heads, the shape of the dies and the place of evacuation. The main types of dispensers: flour - auger, belt and rotor; waters - rotor, piston and rotor-scoop water. Dough mixer presses depending on the duration of the batch and the place of evacuation can have one, two or three in series [...]

LPSH-500 press. The main nodes of the LPS-500 screw macaroni press are a dosing device, a three-chamber kneading machine with a drive, a pressing housing with a drive, a pressing head for a round matrix with a die changing mechanism and a blower. All of the above nodes are mounted on a metal frame installed on four supports. In fig. 4.3 is a diagram of this press.

Press LPSh-500. The main components of the LPSh-500 screw pasta press are a dosing device, a three-chamber mixing machine with a drive, a pressing case with a drive, a pressing head for a round matrix with a die change mechanism and a blower. All of these nodes are mounted on a metal frame mounted on four supports. In fig. 4.3 is a diagram of this press. The press is equipped with a cutting mechanism, water ring [...]

Matrices are made of durable corrosion-resistant materials, such as LS59-1 brass (GOST 15527 - 70), BrAZh9-4l solid phosphor bronze and 1X18H9T stainless steel (GOST 5949 - 75). In the absence of stainless steel, it is replaced with less scarce chrome steel of grades 2X13 and 3X13 (GOST 5949 - 75). Types of matrices. Round matrices (Fig. 4.5). Installed in screw presses for [...]

The dies are made of corrosion-resistant, durable materials, such as brass LS59-1 (GOST 15527 - 70), solid phosphorous bronze BrAZh9-4l and stainless steel 1X18Н9Т (GOST 5949 - XNXXX GOST 75-XNXX) In the absence of stainless steel, it is replaced by a less deficient chromium steel of the grades 2XXNNUMX and 13X3 (GOST 13 - 5949).

Maintenance of screw pasta presses includes the following list of operational measures: preparation of the press for operation, start-up and exit to operating mode, operating rules and safe operating mode. To prepare the press for work it is necessary: ​​to check the presence of lubricant in all rubbing parts; pour the gears of the main drive, dispenser and kneading machine to the required level with industrial oil [...]
