Injector Axial Displacement for Heat Transfer Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing injectors for heating liquid products, especially viscous ones, face issues with heat transfer capacity degradation due to product deposits, leading to uneven heating and post-evaporation, as the radial extent of the mixing chamber influences heat input and transfer conditions, and current methods fail to effectively manage these deposits.
Innovation Solution
The solution involves using physical parameters like vibration frequency, temperature difference, and pressure difference to automatically control the axial displacement of the mandrel-shaped displacement body within the injector, adjusting the radial extent of the mixing chamber to maintain consistent heat transfer performance, thereby preventing deposit formation and ensuring complete condensation of vaporous heat carriers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If the radial extent of the mixing chamber is increased to improve heat transfer, then heat transfer capacity is improved, but product deposits form more readily on the hot components
Solution Approach 1:
The displacement body is made axially movable to dynamically adjust the radial extent of the mixing chamber. During operation, the system automatically adapts the mixing chamber dimensions to optimize heat transfer while preventing product deposits, transforming a static component into a dynamic control element that responds to process conditions.
Solution Approach 2:
The invention changes the physical parameter of the mixing chamber radial extent by axially displacing the displacement body. This parameter adjustment allows the system to modify heat transfer surface area and product layer thickness, thereby controlling both heat transfer capacity and deposit formation tendencies.
2Productivity
If the product layer thickness is reduced to improve heat transfer efficiency, then heat transfer is improved, but the mixing chamber radial extent must be precisely controlled to prevent deposits
Solution Approach 1:
The system incorporates automatic control that monitors process conditions and adjusts the axial position of the displacement body accordingly. This feedback mechanism maintains optimal product layer thickness and mixing chamber dimensions, preventing product deposits while ensuring efficient heat transfer without requiring manual intervention.
Solution Approach 2:
The displacement body is designed to be automatically displaced by control means that respond to process conditions. The system self-regulates the mixing chamber radial extent and product layer thickness, maintaining optimal heat transfer conditions and preventing deposits through automatic adjustment rather than external control.
3Device complexity
If manual displacement of the displacement body is used, then device complexity is reduced, but heat transfer performance cannot be automatically maintained
Solution Approach 1:
The invention introduces automatic control means that monitor process conditions and adjust the displacement body position accordingly. This feedback system maintains consistent heat transfer performance by continuously adapting to changing process conditions, eliminating the need for manual intervention while ensuring reliable and consistent operation.
Solution Approach 2:
The manual mechanical displacement system is replaced with automatic control means that can be electrical, pneumatic, or hydraulic. This substitution eliminates manual operation, maintains consistent heat transfer performance through automated regulation, and adapts to changing process conditions without requiring human intervention.
4Speed
If superheated steam is used as vaporous heat carrier, then heating speed is improved, but complete condensation cannot be achieved in the injector
Solution Approach 1:
The system dynamically adjusts the mixing chamber radial extent by axially displacing the displacement body to optimize condensation conditions. This dynamic adjustment ensures that superheated steam condenses completely in the mixing chamber, achieving reliable heat transfer while maintaining high heating speed.
Solution Approach 2:
The invention changes the physical parameters of the mixing chamber (radial extent, product layer thickness) to optimize the condensation of superheated steam. By adjusting these parameters, the system achieves complete condensation while maintaining the high heating speed associated with superheated steam usage.

AI summary
The invention relates to a method for introducing a vaporous heat carrier into a liquid product, in particular a food product or beverage, and in this case in particular viscous products, for example desserts, sauces or concentrates, in which method the vaporous heat carrier heats the liquid product in order to form a germ-free product, and also to an injector for carrying out the method. The object of the present invention is to provide a method of the generic type and an injector for carrying out said method, with which method and injector, in particular, a reduction in the heat transfer capacity of the injector is prevented over the entire production time. In the context of the method, this is achieved in that three physical measurement variables which can be detected during operation of the injector are used as indicators of the formation of product deposits, at least one of said three physical measurement variables being detected, and in that, depending on one or more of these physical measurement variables, an automatically controlled axial movement of the displacement body is carried out in such a way that the heat transfer capacity from the vaporous heat carrier (D) into the liquid product (P) remains the same.
