production laboratory (physical-chemical, microbiological)

Frozen raw materials and dry products are delivered by road to 20 tons twice a day, unloaded on a closed ramp by electric cars and stored in the raw materials refrigerator and dry products warehouse.

The frozen fish protein is defrosted and fed into the kneading room.

The rest of the raw material (salt, sugar, starch, additives, etc.) is weighed according to the master recipe and supplied to the production line in the production workshop, where all technological operations take place in a continuous flow: cooking, molding, pasteurization, cooling, freezing.

Finished products are packaged in cardboard containers and stored in the refrigerating chamber until sale, exported by auto-refrigerators of 20 tons twice a day.

Technological and sanitary-microbiological control of production and finished products is carried out in the production laboratory of the workshop in accordance with the "Instruction on sanitary-microbiological control of the production of food products from fish and marine invertebrates" and the sanitary rules SP 1.2.73199 "Safety of work with microorganisms of groups III - IV pathogenicity and helminths."

The production laboratory is designed to work with microorganisms of pathogenicity group III.

When processing fish semi-finished products, only waste from packaging materials is formed, which are temporarily stored in the waste room, and then exported to the city landfill under an agreement with the housing and communication services of the city..

The workshop for processing fish semi-finished products has in plan dimensions of 90m x 50m, one-story, two-span, span length - 25 meters, height of the workshop to the bottom of projecting structures 5.4 m.

In the production building there is one production workshop with an area of ​ ​ 2051.03 m2, refrigerating chambers with an area of ​ ​ 29.80 m2, 449.09 m2 and 986.40 m2, corridors, ramps, auxiliary rooms.

To the left of the main entrance at the end of the production building there is an administrative - household block with dimensions in the plan of 27 m x 50 m, in which there are rooms, household rooms, bathrooms, showers, a dining room - a dispensary, rooms for sanitary treatment of clothes, laboratories. The height of these rooms is 3 m. The building of the workshop and ABK is one-story, frame, without a basement, with a technical attic room.

To the right of the main entrance along the axis "25" to the building is attached a production - auxiliary unit with plan dimensions of 15 m x 45 m, this unit includes: a boiler room with liquid fuel, a room for storing stove fuel, a compressor room, a workshop, a packing material room, a transformer substation, a corridor. The height of the premises is 5.5 m and 4.4 m. The building is one-story without a basement, with an operated flat roof.

The building of the main production building and the administrative - domestic block have an IV degree of fire resistance, the building of the production - auxiliary block - II.

1.3 Design Solutions

Structural elements of the building in axes "124" are performed:

- foundations - padded cast-in-situ railway piles with a length of 6 and 4 m are arranged using a casing metal pipe with a fifth. Pedestals for columns from monolithic railway and ribbon .

- building frame - metal, consists of rafter trusses with a length of 25m, 15m and 10m; substructure trusses 10 m long and 7.5 m long with support on steel columns. Trusses are designed from steel bent profiles of closed rectangular section. Columns - steel from rolling I-beams of box section from two channels and from steel bent closed profile of rectangular section.

Lower belts of rafter trusses are fastened by vertical ties and struts, metal runs, cross ties and struts are laid along upper belt of trusses, which provides spatial rigidity of overlapping disk. The project also provides vertical cross links along the columns of the structural frame.

- external walls from the level of the top of the pile walls to the level of the top of the floor are made of railway basement plates, above - from wall panels of the Metalloplast plant of the Republic of Poland of the Sandwich type with a thickness of 80 mm (polyurethane foam insulation in steel sheathing);

- internal walls and partitions of wall panels 60 mm, 120 mm thick. The walls of the refrigerating chambers are adopted with a thickness of 160 mm. Fire-prevention walls on an axis "6" and "Zh" of wall panels 120 mm thick with nonflammable heater from stone cotton wool like "Paroc".

The block of production and auxiliary premises in axes "2425" is separated from the main production building along the axis "24" by a brick fire wall.

The production and auxiliary unit is provided from structures corresponding to the building of the II degree of fire resistance:

- on the pile base tape pile-bars are made, then brick walls and railway coverings with a soft roll roof. Walls are insulated from the outside with stone wool and sheathed with steel profile sheets.

Along the perimeter of the building, when entering the premises, monolithic railway stairs with platforms and ramps for transformer, packaging and workshop rooms are arranged.

Windows in the building were used of individual manufacture with a single-chamber glazing package made of ordinary glass in PCV bindings and stained glass windows for ABK in the axes "AD" and "15" in aluminum bindings.

External doors of individual manufacture are insulated plastic, internal ones are also made of plastic, except for special-purpose doors installed in fire walls and made of metal with a fire resistance limit EJ60. There are also special metal doors in the transformer substation and in the refrigerating chambers (insulated with automatic and manual opening). Heat engineering characteristics of the applied designs of walls, overlappings, floors, windows and doors meet the requirements Construction Norms and Regulations of II379.

1.4 Architectural and artistic solutions

Internal walls, partitions and ceilings made of Sandwich panels do not require additional decoration. The walls in the industrial annex room are plastered, the ceilings are masked and all surfaces are covered with emulsion paint, in the bathrooms and shower walls are lined with ceramic tiles.

Floors in most rooms are concrete monolithic of the "Koradur" type, in domestic rooms made of ceramic tiles, in administrative rooms - carpet, with fire - technical characteristics of groups B1, D1.

Floors with polystyrene foam insulation are provided in the rooms of refrigerating chambers.

Exterior finishes for Sandwich wall panels are not required. The walls of a production and auxiliary extension made of brick with insulation with stone cotton wool and plating with profiled steel sheet also do not require additional finishing.

1.5 Engineering and sanitary equipment
