Description

A kind of sterilizing unit

Technical field

The utility model relates to the technical field of wet heat sterilization in food processing, relates in particular to a kind of device that fibre-bearing and high viscosity materials material are carried out to sterilization of being applicable to.

Background technology

For reducing harmful bacteria amount of survival in food, avoid the absorption of viable bacteria to cause the mankind poisoning.Reach the stabilisation of food quality, effectively extend the shelf-life of food, realize by the mode of various sterilizations in commercial process kind.With the method for wet heat sterilization be continuous effective to low concentration low viscosity material, but to the sterilization of fibre-bearing and high viscosity materials material, conventionally adopt to directly passing into steam in soybean milk boiling tank and carry out intermittent operation, or multiple tank is arranged side by side, complex structure, floor space is large, operating cost and system cost high.

Summary of the invention

In order to solve the poor continuous wet heat sterilization of fibre-bearing sticky material of the mobile property of high concentration and the problem of non-scaling, it is a kind of simple in structure that the utility model provides, easy temperature control system the high concentration poor fibre-bearing sticky material of property that flows is carried out to the steam direct injection sterilizing unit of continuous sterilizing.

For achieving the above object, the technical solution adopted in the utility model is:

A kind of sterilizing unit, is applicable to fibre-bearing and high viscosity materials material to carry out sterilization, comprises the steam blast pipe in housing and housing, and described steam blast pipe is combined by flange with housing; In steam blast pipe, by steady pin, material distributor is installed, described material distributor below is vapour material hybrid chamber, and vapour material hybrid chamber bottom is material outlet; On described steam blast pipe sidewall, be distributed with steam dispersion hole; On the housing above material distributor, be provided with steam inlet duct.

As a kind of preferred version of sterilizing unit described in the utility model, described steam dispersion hole is taper, the vertical line of opening direction and steam blast pipe sidewall is 10-40 ° of angle, and preferred steam dispersion hole opening direction and steam blast pipe sidewall vertical line are 20-30 ° of angle.

As a kind of preferred version of sterilizing unit described in the utility model, symmetrical two steam inlet ducts on the housing of described material distributor below, two steam inlet duct other ends are all communicated with steam air supply pipe.

As a kind of preferred version of sterilizing unit described in the utility model, the described import of steam blast pipe and material outlet place are equipped with movable joint, and good airproof performance is convenient to dismounting simultaneously and changes.

Beneficial effect:

This device can carry out continuous sterilizing to the thickness fibre-bearing material of solid content 42% through installing material distributor additional, it is not easy to form fouling, easy temperature control system, operating temperature requires between 80-140 DEG C, to regulate according to different process, this uperizer is particularly useful for the product to not carrying out by heat-exchangers of the plate type well processed, has good economic worth.

Brief description of the drawings

Fig. 1 is sterilizing unit structural representation described in the utility model.

Fig. 2 is the top view of sterilizing unit described in Fig. 1.

Wherein: 1,5, steam inlet duct 2, flange 3, steam blast pipe 4,6, movable joint 7, material outlet 8, housing 9, material distributor 10, steady pin 11, steam dispersion hole 12, vapour material hybrid chamber 13, steam air supply pipe 14, flange

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

Embodiment 1

As shown in the figure, a kind of sterilizing unit, comprise the steam blast pipe 3 in housing 8 and housing, described housing 8 passes through flange 2 combinations with steam blast pipe 3, steam blast pipe 3 tops are provided with the import of movable joint 4 as sterilization material, in steam blast pipe 3, by steady pin 10, material distributor 9 is installed, material distributor 9 belows are vapour material hybrid chamber 12, and housing 8 bottoms are connected with the discharging opening 7 with movable joint 6.1,5, two sections of

steam inlet duct

1,5 use elbows of described housing 8 outside balanced configuration steam inlet duct are communicated with three-way pipe in housing 8 dorsal parts, and three-way pipe end openings is acting flange 14 upward, is connected with steam air supply pipe entrance 13.Steam dispersion hole 11 on steam blast pipe 3 is the taper of You circular base, the cross section level of position and steam blast pipe, the vertical line of its opening direction and steam blast tube wall is 20 degree angles, steam dispersion hole 11 inwall apertures are 3 millimeters, pitch of holes is 12 millimeters, a material distributor 9 is installed at steam blast pipe 3 centers, material is delivered into steam blast pipe 3 under certain pressure, after material distributor 9 distributes, in vapour material hybrid chamber 12, mix under certain pressure with steam, product is quickly heated up to sterilising temp by the latent heat that steam discharges.

Taking the full powder of wet method soybean as example, 400 kilograms of soybean of not peeling of every batch of material, after immersion, add mill beans liquid (1200 kilograms, water, 900 kilograms, the syrup of solid content 75%) carry out defibrination, defibrination fineness 100% mistake aperture is the screen cloth of 2.5 millimeters, and measuring its solid content by seasoning is 43.6% (w/w);

First steam supply valve is opened through steam air supply pipe entrance 13 and entered steam inlet duct 1 and steam inlet duct 5 carries out wet heat sterilization from both direction to housing 8 gut lines, initial steam pressure 0.2-0.25MPa keeps 4 minutes, unlatching send stock pump that the slurries of milled are sent into sterilizing unit by underflow pump through steam blast pipe 3, adjust vapour pressure is 0.5-0.6MPa simultaneously, inlet amount is adjusted into 5 tons/hour, insulating tube end thermometer is shown as 120-130 DEG C, be cooled to 70-80 DEG C through chimney cooler, after throwing 5 batch of materials and producing continuously, testing product sanitary index: clump count cfu/ml :≤100, coliform MPN/100ml≤30, mould cfu/ml≤10, bactericidal effect ideal, disassemble after sterilizing unit, without obviously fouling.
