ES2222824A1 - Preparation of a mollusc shell based culture material comprises sterilization, heating and grinding, for vibratory sieving for bivalve culture - Google Patents

Abstract

The preparation of a mollusc-shell-based culture material consists of sterilization of the shells, heating for 15 minutes at 120 degrees C, and grinding in a 1000 rpm centrifugal mill for 15 minutes. Vibratory sieving to 1-6 mm granulometry is followed by storage and packaging, for use e.g. in ponds for bivalve culture.

Description

Manufacturing procedure of a product a mussel shell base used in nurseries and production beaches of bivalve culture.

Object of the invention

The present invention relates to a manufacturing process of a shell-based product mussel used in nurseries and crop production beaches of bivalves

Background of the invention

The nurseries and beaches of crop production of bivalves have problems to develop conveniently that type of shellfish mainly due to the lack of calcium carbonate which is the fundamental substance for the development of these mollusks.

Description of the invention

The process of the invention is intended and designed to remedy the aforementioned problem that Causes the lack or lack of calcium carbonate presented by nurseries and beaches producing bivalve crops.

This solution involves using shell mussel that is conveniently prepared with the procedure of the invention.

The procedure includes:

- receive in a hopper tower the mussel shell from cookers and / or factories preserves.

- The shell of the mussel once sterilized is it is subjected to a drying process at a temperature of 120º centigrade for 15 minutes.

- The mussel shell is ground in a mill centrifuge whose shaft rotates at 1000 revolutions per minute for 15 minutes

- The crushed product is passed through a sieve vibrant that allows to obtain a grain size between 1 and 6 mm.

- The product with this particle size is packaged for transport and marketing.

Description of a practical embodiment of the invention

In the application of the process of the invention, the shell is received in a tower.
hopper.

This shell once received is sterilized and a dryer is passed which is at a temperature of 120 ° C and Hold on it for 15 minutes.

The treated product passes a process of crushing in a centrifugal mill that rotates at 1000 revolutions per minute and the product is subjected for 15 minutes.

Once crushed mussel shell is passed by a vibrant sieve that allows to obtain a grain size between 1 and 6 mm and then passed to a product hopper screening of which the packaging is carried out.

In the application of the crushed product is cast this one from boats or barges.

The product is thrown on the beaches and spread with rakes in the sand or mixing the product with the own sand

The degree of sand mixing with crushed shell depends or is a function of the amount of calcium carbonate that You need the nursery or beach.
