Continuous Thickening Theory

In a continuous thickener the downward solids velocity with respect to the thickener wall is the sum of the settling velocity of the solids by gravity alone, Vi, plus the downward velocity caused by removal of the thickener underflow, U. The rate at which solids move downward by gravity alone is expressed as the product of the concentration of the solids in a layer, Ci, and the settling ...

As a result, there are now two basic types of continuous thickeners: Conventional and High-rate. Conventional Thickeners These thickeners differ in the way they are built.

1.3: Types of Thickening Agents - Chemistry LibreTexts

In cooking a filling, about 1.5 kg 3 1/3 lb. of sugar should be cooked with the water or juice for every 500 g 18 oz. of starch used as a thickener. Approximately 100 g 4 oz. of starch is used to thicken 1 L of water or fruit juice. The higher the acidity of the fruit juice, the more thickener required to hold the gel.

Thickeners Rheology Guide

Inverse Emulsion Thickeners Conventional emulsions, in technical terms, are oil-in-water emulsions i.e the continuous phase is water. Inverse emulsions are simply the opposite i.e water in oil emulsions with the continuous phase being an oil. Texipol inverse emulsions are manufactured directly from the pre-neutralised liquid monomers

The Science of Thickening Agents — The Culinary Pro

The goal of thickening a soup or sauce is to add viscosity, texture, and mouth-feel, helping the food to linger on the tongue and taste buds. Thin sauces have a more intense and direct flavor impact but will not have as lasting an effect on the palate. Adding a starch thickener helps the sauce cling to the tongue but is can block flavors so they may require more seasoning or flavoring.

The practice of thickening or clarifi ion is usually carried out in decantation tanks employing gravity settling or sedimentation. These tanks are fitted with mechanical scrapers to collect and move the settled solids to the point of discharge, the clear overflow being collected and removed by means of peripheral launders. These tanks, equipped with mechanical scraping devices and launders ...

In a continuous thickener, there is a second flux component, that due to the downward movement of the slurry caused by the sludge being pumped from the bottom of the thickener. Combination of these two downward fluxes results in a criterion with a minimum, which corresponds to the maximum flux the thickener can handle. In principle, this method allows the minimum area to be calculated, and ...
