Scraped-surface heat exchangers are typically used to handle viscous or scale-prone fluids, which may cause scaling or fouling on the heat transfer surfaces.

Typical applications of scraped-surface heat exchangers include:

Food processing: Used in the processing of chocolate, cheese, butter, margarine and other viscous or semi-solid foods.

Petrochemicals: Used in the processing of various petrochemical products, such as waxes, oils and lubricants, which require high-temperature treatment.

Core Front-End Equipment for Butter Packaging, Customized Rapid Crystallization and Homogenization Shaping Solution for Block Butter, Slice Butter and Bagged Butter.

I. Product Overview

MITTIWAY Ultra-Cold Kneading Machine (Scraped Surface Heat Exchanger) is an integrated front-end quench cooling and kneading equipment specially developed and designed for plastic fats such as butter, margarine and shortening. This equipment can accurately connect with the subsequent block butter/slice butter wrapping machine and carton/drum inner bagged butter packaging machine, constructing a full-link butter processing system of "Front-End Rapid Crystallization — Mid-End Precision Kneading — Back-End Efficient Packaging". It effectively solves the industry pain points such as coarse crystals, rough taste, oil separation, sanding and dull luster existing in the traditional natural crystallization process, helping to improve product quality.

II. Core Advantages

• Rapid Crystallization, Quality Upgrade: The instant cooling process inhibits the excessive growth of crystals. The finished oil has a milky white and bright color, a delicate taste without sand feeling, and smooth spreading. There is no oil separation or coarsening during the entire storage period, which significantly improves the market competitiveness of the product.

• Efficient Heat Exchange, Energy Saving and Stability: The customized corrugated cooling crystallization cylinder and narrow gap (7mm) design greatly improve the heat exchange efficiency; the equipment adopts a fully sealed insulation structure, which can meet the demand of 24-hour continuous production, with stable and reliable operation and long-term trouble-free operation.

• Food-Grade Precision Manufacturing, Safety and Compliance: All parts in contact with materials are made of 304/316 stainless steel, and the seals are selected from food-grade silica gel and silicon carbide wear-resistant rings, which fully comply with relevant food hygiene standards and ensure the safety of product production.

• Flexible Adaptation, Multi-Scenario Compatibility: Parameters such as equipment speed, pressure and temperature can be flexibly adjusted, which can be adapted to the production needs of various types of butter such as block butter, slice butter, carton inner bagged butter and drum inner bagged butter. It is compatible with Metway's full range of subsequent packaging equipment, realizing seamless connection and ready-to-use, and reducing equipment adaptation costs.

III. Application Scenarios

• Butter Processing Field: It can be widely used in the production and processing of various butter products such as block butter, slice butter, anhydrous butter and fermented butter.

• Packaging Adaptation Scenario: It can be directly connected with Metway's block butter/slice butter wrapping and cartoning machine, carton inner bagged butter packaging machine and drum inner bagged butter packaging machine, realizing efficient linkage between processing and packaging.

• Extended Application Field: It can be extended to the production lines of various plastic fats such as margarine, shortening and cocoa butter substitute, with a wide range of applications.
