Un comedero autom\u00e1tico se atasca casi siempre por lo mismo: la croqueta es m\u00e1s grande que el paso del tornillo sinf\u00edn que dosifica. Los comederos Producan no llevan sinf\u00edn \u2014dosifican dejando caer el pienso por su propio peso, con un mecanismo de rotor con escobillas patentado\u2014, y por eso admiten croqueta de cualquier tama\u00f1o y forma.<\/p>\n\n\n\n
It's a metal or plastic spiral inside a tube. As it turns, it pushes the kibble towards the outlet. Each turn moves a known volume, and that's where the precision comes from: you can ask for \u00ab45 grams\u00bb and the motor counts the turns.<\/p>\n\n\n\n
The problem is geometric. The gap between the spiral and the wall of the tube is calculated for kibble of one particular size. With larger kibble, or an irregular shape \u2014 lamb and rice kibble tends to be flat and wide \u2014 the piece wedges on edge between the spiral and the tube and the motor stops turning. Sometimes the cut-out trips; sometimes the motor keeps forcing until it breaks.<\/p>\n\n\n\n
El dep\u00f3sito termina en una boca ancha con una rotor con escobillas. El programador la abre el tiempo justo y el pienso cae solo, por gravedad. No hay nada girando, no hay ning\u00fan paso estrecho y no hay ninguna pieza que pueda quedarse trabada contra otra.<\/p>\n\n\n\n
What you lose is precision: the serving is set by opening time, so two feeds can differ by a few grams. What you gain is that it doesn't fail, which is what matters when the unit has to run on its own for three weeks.<\/p>\n\n\n\n

Si el comedero va a estar en un patio o una finca alimentando a un perro grande durante semanas seguidas, lo que no puede pasar es que se atasque, y ah\u00ed nuestro sistema de rotor gana sin discusi\u00f3n.<\/p>\n\n\n\n It's summed up in the guide to choosing an automatic dog feeder<\/a>.<\/p>\n\n\n |
