Problems solved by technology

However, these methods introduce an additional drying step in addition to the reaction step
Moreover, they cannot allow high dry extracts of the reaction mixture: high dry extracts can lead to clogging of the equipment used

Embodiment 1

[0262] Example 1: Salt (HMTBA) 2 Preparation of Ca

[0263] Milk of lime prepared at 30% dry matter was mixed with HMTBA solution having 88% dry matter in a pipeline containing a static mixer with 22.2% milk of lime (based on dry matter used) and 77.8% HMTBA (based on dry matter used). Substance calculation) ratio continuous mixing.

[0264] The contact time was 7 seconds.

[0265] The reaction mixture was then pulverized in a single-effect atomization tower with an inlet temperature of 140°C and an outlet temperature of 79°C by means of nozzles known to those skilled in the art.

[0266] The product was then processed in a fluidized air bed dryer to obtain an agglomerated powder to simulate a multiple effect atomization tower.

[0267] The resulting product has a HMTBA content of 81.4%, a Ca of 11.8% 2+ and a water content of 1.3%. The average particle size was 240 μm and the density was 300 g / L.

Embodiment 2

[0268] Example 2: Salt (HMTBA) 2 Another preparation of Ca

[0269] Milk of lime prepared at 30% dry matter was continuously mixed at 138 kg / H with a 154 Kg / H HMTBA solution with 88% dry matter in a pipeline containing a static mixer to obtain a reaction mixture with 60% dry matter.

[0270] The contact time was 15 seconds.

[0271] The reaction mixture was then pulverized in a single-effect atomization tower with an inlet temperature of 185°C and an outlet temperature of 128°C by means of nozzles known to those skilled in the art.

[0272] The resulting product contained 84.9% HMTBA, 12.0% Ca 2+ and 0.5% water.

[0273] The average particle size was 156 μm (Dv(0.5) by laser granulometry) and the density was 170 g / l.

Embodiment 3

[0274] Embodiment 3: the preparation of the Mg salt of HMTBA

[0275] The magnesium hydroxide suspension with 20% dry matter was continuously mixed at 2.9 kg / H with a 4.3 Kg / H HMTBA solution with 70% dry matter in a line containing a static mixer.

[0276] The contact time in reactive atomization was 7 seconds.

[0277] The reaction mixture was then pulverized in a single-effect atomization tower with an inlet temperature of 140°C and an outlet temperature of 76°C by means of nozzles known to those skilled in the art.

[0278] The resulting product had a HMTBA content of 91.2%, a Mg of 7.4% 2+ and a water content of 1.4%.

[0279] The average particle size was 7 μm and the density was 310 g / L.

Abstract

The present invention relates to powder compositions of a complex between an acid and a metal and to the method for preparing same.

Description

technical field [0001] The present invention relates to a powdered composition of a complexe between an acid and a metal and a method for its preparation. Background technique [0002] Methionine (an essential amino acid) and HMTBA (an analogue of methionine) have very broad applications for humans, as food supplements or pharmaceuticals, and as animal nutrition. Metal salts such as calcium, magnesium or zinc salts may be preferred in their solid form. They can also be used to compensate for deficiencies of elements or trace elements. The most known salt of HMTBA is the dicalcium salt, containing two molar equivalents of HMTBA per mole of calcium, corresponding to the formula (HMTBA) 2 Ca. [0003] From EP 140865 A a process is known for preparing a calcium salt of HMTBA which consists of more than two and less than ten molar equivalents of HMTBA per mole of calcium. These salts are obtained by reacting HMTBA with a calcium source selected from calcium oxide (CaO), calci...
