Abstract

A fermentation device comprises a fermentation container housed within a multilayer insulation bag. The fermentation container includes a basin and a lid that define an interior volume for holding fermentable material. The insulation bag includes five layers: a heat-dampening lining fabric, an integrated heated mat, an insulation film, a cotton insulation layer, and a waterproof outer layer. A controller operatively connected to the heated mat includes a user interface and a timer for regulating fermentation parameters. A temperature sensor having a probe extends into the interior volume and continuously communicates internal temperature data to the controller. Based on the received temperature data, the controller automatically adjusts power to the heated mat to maintain a selected fermentation temperature. The multilayer insulation structure enhances thermal retention and stability, enabling precise and consistent temperature control during fermentation in a compact device suitable for small-scale or residential environments.

A fermentation device for fermenting liquid dough or other fermentable substrates, comprising:

a fermentation container comprising a basin and a lid, wherein the lid is coupled to the basin to define an interior volume and an exterior surface, the interior volume configured to hold liquid dough or other fermentable substrates;
an insulation bag surrounding the exterior surface of the fermentation container, the insulation bag comprising:
a body portion and a lid portion that together define an interior cavity, wherein the basin of the fermentation container is contained within the body portion of the interior cavity and the lid of the fermentation container is covered by the lid portion of the insulation bag;
and
a multilayer structure comprising a plurality of layers including:
a first layer comprising a lining fabric positioned innermost relative to the fermentation container;
a second layer comprising a heated mat;
a third layer comprising an insulation film;
a fourth layer comprising a cotton material;
and
a fifth layer comprising a waterproof material positioned outermost;
a controller operatively connected to the heated mat and configured to regulate a temperature of the heated mat, the controller comprising:
a user interface configured to receive user input and generate output displays;
and
a timer configured to facilitate timed fermentation processes;
a temperature sensor operatively coupled to the controller, the temperature sensor comprising a probe that extends into the interior volume of the fermentation container and is configured to:
continuously measure an internal temperature of the interior volume;
and
communicate electrical signals indicative of the internal temperature to the controller;
wherein the controller is configured to display the internal temperature on the user interface and automatically adjust the temperature of the heated mat to maintain selected fermentation conditions within the interior volume.
