Homogeneity of mixes – Summary of experimental dat obtained by Tecaliman
In addition to the data published in Special Report no. 41, the base data compiled by Tecaliman between 1993 and 2001 may form the basis for comparing future results. Over the course of the period up to 2001, Tecaliman conducted 364 assessments of tracer dispersion, under all conditions. These assessments were carried out as pilot […]
Method for measuring bulk density, tap density and the Hausner ratio for additives and feedstuffs
Following the purchase of a new powder compac-tion apparatus, Tecaliman decided to modify its measurement procedure for bulk and tap densi-ties, and the resulting Hausner ratio. The objective was to arrive at a procedure similar to the measu-ring technique used by Carr (1965), as applied to the Hosokawa apparatus. Abdullah and Geldart (1999) demonstrated that […]
Identification of high risk points associated with the use of additives in plants
The aims of this sheet are to encourage plant managers to be more vigilant, to lead them to question themselves regarding their practices and to make them aware of the HACCP method (Tecaliman 1996 : i’Tec_S2). This sheet has been drafted using the results of the program implemented by TECALIMAN, with the assistance of the […]
Establishing decontamination scales via the pelleting of pig, laying hen, broiler and turkey feeds
European regulations 183/2005 of 12/01/05 and 2160/2003 of 17/11/03 are driving the animal feed sector to strengthen its control over the risk of salmonella infection. This legislation was incorporated into French law under the order of 23 April 2007, which focuses specifically on the treatment of feedstuffs destined for breeding laying hens. The requirements laid […]
Technical rules for assessing the bacteriolytic effectiveness of a pelleting line or a heat treatment
The implementation of European regulations 183/2005 of 12/01/05 that establishes feed hygiene requirements, and 2160/2003 of 17/11/03 on control of salmonella in the food chain led to the publication in the French Official Journal of the Order of 23 April 2007 relating to approvals of business operators in the animal feed sector. This order introduced […]
Study of microbial contamination in animal feed production units
This document provides a summary of a study financed by TECALIMAN, the ACTIA and the PAYS DE LOIRE REGION, all of the results of which were published in i’Doc_S7 of July 1996.
Effect of particle size on the energy efficiency of the Milling-Pelleting Pair
In bibliographical terms, Seeling and Wulff (1946), and Kumar (1973) describe 3 fundamental mechanisms of compression control: Slippage directly related to settling Elastic or plastic deformation Fragmentation This third point suggests that a product that is “too coarse” would be likely to increase the press power demand during its agglomeration. While several authors (Smith, 1962, […]
Pilot study on micro-ingredient carry-over via a bucket elevator : Method
This datasheet describes the equipment and methods developed during the POUSSALIM research project (i’Doc_T16) in order to assess micro-ingredient carry-over on a bucket elevator. This technical datasheet links up with i’Tec_T13.
Comparing internal tracers/external tracers
A mix component referred to as a tracer is used to assess mix homogeneity or the level of carry-over at industrial sites. There are two types of tracer: • internal tracers: a formula ingredient • external tracers: an external agent supplementary to the formula The methods used to select a tracer to assess mix homogeneity […]
Key takeaways from O’Congrès 2025
As every year, Tecaliman is proud to organize its O’Congrès, a place for meetings, discussions and information reserved for professionals in the sector! This event is held every year at Espace Beausoleil, in Pont-Péant, near RENNES, on the Monday before SPACE. In 2025, the theme was: Strategic Plan for Animal Nutrition: What changes for our […]
