Description
Изобретение относитс к способам жидкосхной обработки шкур, в частности к способам консервировани методом тузлуковани . Способ может быть применен так же при проведении отмочных операций, крашени и дубле ни в кожевенно-меховом производстве . Скорость любой жидкостной оСрабо ки шкур определ етс интенсивностью процессов массообмена в системе раствор - шкура . При консервировании методом тузл ковани скорость прохода влаги из шкур в раствор и скорость перехода соли из раствора в объем шкуры опре дел ет продолжительность этого процесса . Фактором, замедл ющим скорость перехода, вл етс образование между шкурой и жидкостью зоны с низ кой концентрацией соли в виде поверхностной жидкостной пленки. Известны способы консервировани шкур предусматривают разрушение это пленки путем многократного перемешивани шкур в консервирующей жидкости при взаимном трении их друг о друга и при воздействии на них стенок, выступов 1 , Известен способ консервировани шкур путем обработки их раствором соли с применением циркул ции и барботировани раствора. Пузырьки воздуха способсвуют многочисленным местным разрушени м зон с низкой концентрацией соли 2. Вышеуказанный способ имеет недостаточную интенсивность массообмена, что приводит к необходимости вести процесс консервировани несколько суток. Целью изобретени вл ето повышение интенсивности обработки. Это достигаетс за счет того, что шкуры предварительно закрепл ют в расправленном состо нии, в обработку консервирующей жидкостью осуществл ют в присутствии твердых частиц, наход щихс в псевдоожиженном состо нии. Кроме ТОГО, в качестве твердых частиц используют крошку каменной соли в количестве 30-60% от веса жидкости. На чертеже изображена установка дл консервировани шкур. П р к м е р. Ъ бак 1 засыпакг частицы каменной соли 2 в количестThe invention relates to methods for the liquid processing of hides, in particular, to the method of preservation by the method of heathing. The method can be applied also when conducting master operations, dyeing and duplicate, or in leather and fur production. The speed of any liquid skin is determined by the intensity of the mass transfer processes in the solution – skin system. With canning and canning, the rate at which moisture passes from the skins to the solution and the rate at which the salt transitions from the solution into the skin volume determines the duration of this process. A factor slowing down the rate of transition is the formation of a zone with a low salt concentration in the form of a surface liquid film between the skin and the liquid. Known methods of preserving hides provide for the destruction of this film by repeatedly mixing the hides in a preserving fluid when they are mutually frictioned against each other and when they are exposed to the walls, protrusions 1. Air bubbles cause numerous local destruction of zones with a low salt concentration of 2. The above method has insufficient mass transfer intensity, which makes it necessary to conduct the preservation process for several days. The aim of the invention is to increase the intensity of processing. This is achieved due to the fact that the skins are pre-fixed in the expanded state, into the treatment with preserving liquid is carried out in the presence of solid particles that are in a fluidized state. In addition to TOGO, crumb rock salt in the amount of 30-60% by weight of the liquid is used as solid particles. The figure shows an installation for preserving hides.
