DFN TG - 76 Clip casing heat exchanger,Hong Kong price supplier

1, the product features

DFN TG - 76 clip casing heat exchanger, applies to stainless steel heating or cooling without corrosive liquid, combination of multiple sets of straight pipe heat exchanger, according to user's process requirements, in the same unit at the same time be heated, heat preservation, heat recovery and cooling. Complete set of equipment can also be the heat Sterilization of material or cooling temperature automatic control and records, and the unqualified material automatically to deal with, the equipment has high in thermal efficiency, compact structure, reliable operation, stable performance, long operation time and operation convenient cleaning and maintenance, etc.

2, the main purpose and scope of application

Because the DFN TG - 76 clip casing heat exchange tube inner surface after polishing treatment, small resistance, the wall coking of the material under the condition of high temperature phenomenon is improved greatly, as a result, it can be widely applied in the plate heat exchanger can't application occasions, it besides can deal with fresh milk, soy milk, tea drink, FRUIT JUICE beverages, also suitable for high viscosity or with particles and fibres of other liquid food and sauce, chicken juice production line.

Working principle and design standards

1, the working principle of the

TG76 clip casing heat exchanger is made of different diameter straight pipe concentric casing, and are connected by a u-shaped bend. In this kind of heat exchanger, a fluid tube, the other a fluid clearance, both can get higher velocity of flow, heat transfer coefficient is bigger. In addition, in the casing heat exchanger, two kinds of fluid can be pure counterflow, logarithmic mean driving force is larger. Casing heat exchanger is simple in structure, can withstand the pressure, the application is convenient, can according to need to increase or decrease in number of section). Especially because of casing heat exchanger and heat transfer coefficient is large, the advantages of heat transfer driving force big and strong to withstand high pressure, in the product viscosity large material (stabilizer or sauce, chicken juice, etc.) used in heat exchanger is almost all of the bushing.

DFN TG - 76 clip casing heat exchanger equipment in addition to a host, including material balance tank, hot water tank, centrifugal pump, steam pipe, water heater, meter boxes and associated valves and piping components, material heating, send and return, its temperature control all by instrument box for automatic control and continuous records, in order to monitor production process to check material sterilization quality. Equipment heat sink materials, material balance, heat pumps and pumps are installed on the host side, instrument box according to user requirements in another place.

2, the design standard

Heat transfer surface consists of a set of internal straight tube on both ends. Pipes external shell and with O ring seal. - this kind of design can unscrew the end joint, type O ring seal removed from a main line for inspection and replacement.

Installation instructions:

1, the installation of TG76 clip casing heat exchanger is simpler, equipment placement level shall be maintained. In general, don't have to land bolt is fixed. In pipe installation, material and medium should be installed at the inlet of the valve to control flow, after the equipment localization, sealing ring is missing should check the line pipe will tighten the joint joint after the equipment is in place, according to the logo on the device connected to the material, the medium and so on various pipes. After checked, clean up the environment.

2, working conditions, according to the product technical performance and technical requirements, the user can equipped with the appropriate pump with this product.

Cleaning and disinfection of the equipment

Equipment should be thoroughly cleaned before the formal use, this should be complete cycle of equipment with hot alkaline cleaning, to remove wall of pipeline caused by dirt, then use high temperature hot water instead of material cycle 20 ~ 30 minutes in the equipment, disinfection. With hot water system of complete sets of equipment, as long as the water in the material balance of the tank, according to the sequence of operation can be carried out on the equipment cleaning and disinfection treatment.

Equipment after each use, should be in the following order for cleaning, in order to keep the equipment clean.

1, will the residue out equipment with water, until out of clear water.

2, with 80 ~ 85 °C, the concentration of 1 ~ 1.5 sodium hydroxide solution circulating in the equipment cleaning for 20 minutes, reoccupy clear water is alkaline ejection.

3, the nitric acid solution with concentration less than 1%, heated to 80 °C ~ 85 °C, circulation after 20 minutes with water ejection, with about 40 °C water clean again.

4, with 0.5% sodium hydroxide solution is heated to a temperature of about 40 °C, cycle for 10 minutes, and then the residual liquid ejection with water, then with about 40 °C water to clean.

User units such as CIP cleaning system, can according to the CIP cleaning procedures for cleaning.

Equipment maintenance and maintenance

1, in the process of production, due to the straight tube fouling gradually, make the heat transfer effect will be reduced, the temperature of the heating medium will gradually rise, the scale is more serious, so should be regularly check whether straight pipe to clean thoroughly, if there are products, such as scale, coking, incrustation layer adhesion.

2, equipment heat straight pipe at each end of the rubber seal in the equipment operation after a period of time, should be in
