Description

Mechanization steam soaking scalding animal or fowls feather method and equipment

The present invention will provide a kind of employing mechanization steam soaking scalding animal or fowls feather method and equipment.

Soaking ironing process before the livestock and poultry depilation at present, is in the hot water water of 60～70 ℃ of temperature, with livestock and poultry in batches, or artificial, or by mechanical means, continuously lose into hot-tub stir soak boiling hot; Perhaps be suspended on the mechanical pipeline, continuously boiling hot by soaking in the hot water in the pond.This hot water soaks ironing process, can guarantee in livestock and poultry depilation operation filoplume to be sloughed.But hot-tub soaks to scald its shortcoming: livestock and poultry blood juice, just liquid and the fat that can dissolve enter and understand breed bacteria in the hot water, and boiling hot livestock and poultry are soaked in pollution continuously; Hot water soaks the raw material of the further product of filoplume conduct that scalded, and quality descends, and economic benefit has loss; Big with the hot water amount, the energy consumption height; Discharge of wastewater, contaminated environment is more serious.

The purpose that the present invention proposes is at the problems referred to above, to adopt the method and apparatus of mechanization steam soaking scalding animal or fowls feather; Make livestock and poultry in soaking the process of scalding, no longer contaminated, the filoplume quality is not damaged, and saves the energy and water consumption, reduces the pollution to environment.

The technical scheme that the present invention provides:

Livestock and poultry after pipeline (underslung or roller) will be slaughtered deliver into that steam channel is indoor, livestock and poultry in the indoor conveying of steam channel forward, the vapor (steam) temperature of hectic fever is controlled at about 60～85 ℃ on every side, and press certain mode mobile " stirring " and arrive on one's body the livestock and poultry, stir filoplume, make the fatty thermosol of filoplume root, and lose the ability of clinging filoplume, and filoplume soaks and scalds the operation end, and livestock and poultry enter the depilation operation.

Suspension conveying line here or rolling pipeline are accepted the control of control system, can infinitely variable speeds; Control system mainly contains motor, speed changer and electrical control cubicles (comprising the infinitely variable speeds switch) and forms.

The vapours that steam channel is indoor is by the steam feed arrangement, steam blasting booster, and vapour-recovery unit provides after alone or in combination separately.

Wherein, the gate valve switch of steam feed arrangement is controlled by temperature control system.The size of the quantity of steam of steam feed arrangement feed path chamber has determined the temperature height of the indoor wet-hot steam of passage.Conversely, the temperature that steam channel is indoor provides temperature data to sensor or detector; Sensor or detector after amplifier amplification or conversion, are controlled opening or closing of steam gate valve with the temperature signal that records.The said temperature control system can be controlled at the temperature of steam channel chamber and soak on the best region that scalds filoplume.This zone can be selected between 60～85 ℃ according to the speed of livestock and poultry conveying.

Steam blasting booster is the steam that the steam feed arrangement is provided, in some way " stirring " stir filoplume on one's body to livestock and poultry, allow filoplume soak and scald evenly.This air blast power assisting device can be a series of fans of arranging by certain way, or connects the device of a series of blast orifice on air blast overall channel.

Vapour-recovery unit is an air extractor.It can be independent, also can be to form the loop apparatus of bleeding with air blast with the steam blast device.This device can be saved heat energy.More obviously be, can strengthen the effect of steam blasting booster " stirring " wet-hot steam, and, be recovered to filoplume and reclaim in the filter bag simultaneously the indoor showy filoplume of steam channel.

If it is indoor that the depilation plumage operation after livestock and poultry are soaked and scald also is arranged on steam channel, vapour-recovery unit just can directly reclaim the filoplume of depilation operation, alleviates or eliminates the pollution of operation to environment of losing hair or feathers.

The steam feed arrangement of above-mentioned steam channel chamber, steam blasting booster, and all devices such as vapour-recovery unit in design, can all or partially be provided with separately, also can be all or mix partially and be provided with.

Livestock and poultry are soaked the whole process of scalding filoplume through steam channel chamber, just as what carry out in hot water.Different is, the one, and be medium with hot water, the one, be medium with steam.Soak the time of scalding or soak boiling hot speed, and soak the relation of scalding between the temperature,, and lose the state that clings the filoplume ability and decide according to filoplume root fat thermosol.The speed of as long as this adjust pipeline and temperature control system.

In order to reduce the indoor temperature leak of steam channel.In the import and export of passage, the semiclosed door of number fan is set.Semiclosed door can be the rubber formula, also can be spring or upright piece pulling formula or revolving.
